Is it just me, or is SRT strenuous compared to DRT?

In simple, theoretical, terms SRS is a 1:1 MA and MRS is 2:1

Think about how this applies to moving the same distance and the amount of effort used.

The total energy to move the same distance in either system is the same.

Yep, same energy, more power with SRS.
 
Initial pull on SRS ascent cycle is going to be more work. As mentioned SRS climbers become very efficient distributing and equalizing load to their legs, core and upper body so it is not as noticeable as you might think comparing 1:1 to MRS 2:1.

Old man talking:
At some point in my SRS climbing development (pre-Rope Wrench) I was self-tending a short tethered Microcender as main ascender with a long footloop and a foot ascender on my free foot. I had a hitch below the Microcender that just rode the rope and grabbed on sitback. I could rope walk continuously until I needed a breather on long ascents.

I was still climbing MRS after SRS got me where I was going. I realized though that I wanted to have the same ascent ergonomics: body upright, no sitting back between pulls, MRS or SRS. Just keep going with everything self tending until I reached where I was going.

That’s a long way of saying that MRS climbing should follow the same rules as SRS ascent ergonomics. The ascent motion differences become flattened except there’s the progress/ascent time differences between 2:1 and 1:1.

It’s frustrating to go a long vertical distance 2:1 once you’ve tuned in your SRS ascent style. Probably because my body is so tuned to SRS ascent, MRS feels like it is more work on ascent.

The work done is equal, of same achievement that itself takes matching effort_X against to overcome.
DdRT just more in powerband due to the 'transmission' gear shift to 2:1;
@co$t of more friction for the redirect arc that SRT doesn't have.
So i kinda would vote for more total effort in DdRT due to added friction component/co$t of conversion of the transmission to 2/1.
 
Honestly I have not climbed MRS in 10 years. Tried to a few times and changed over after a few. SRS just works for me every tree. A crane job is my exception but I am just getting a ride setting slings the rapping to make cut. Keep at it, you will get the lightbulb going on.

Hello All,

I'm a recreational climber, exploring all the modes. I am enjoying both SRT and DRT.

There's no doubt that SRT allows for a speedy ascent, however I do find it to be a bit strenuous. Perhaps I'm not positioning my body properly...or something I don't understand. I find hold my upper body vertical and close to the rope to be a bit more fatiguing.

Am I simply an aging lamo, or is this the trade off?

Thanks.

Post a video of you ascending

Having short inseam and watching someone with long legs footlock or footcam well can be demoralizing.

Proud to say I’m built like a over fertilize cottonwood planted by the equator, wesco has to check with the heads in the custom boot plant to see if they could make a pair to fit my ankles.. With my new tribe onyx I had to add the leg loop pads, but still ran out of adjustment (on the small side) for them to sit snug.

Me too, brother. After decades of doing everything with MRS I will only use it for simple descending movements like crane work.

I can guarantee that I would not still be climbing without SRT.

My sentiments exactly. MRS for climbing is a thing of the past for me. The MA is not a pro in mind, no deal breaker. I do not miss it ever.

I’m probably extreme but I don’t like MRS even when I’m using my lanyard as a second short rope ;-)

I've seen your SRT lanyard stuff, moss. Are you always keeping a retrieval tail with you when you're using your lanyard in this manner?

Edit: ...or are you going always going up to where you set it up and retrieving it, etc.? I can't offhand think of a way that you could do that, given what (little) I remember of your lanyard.

Over the years I've talked with several climbers who were around fifty years old who changed over to SRT. They all thought that their climbing days were over because of achy joints from a career of footlocking and yarding ropes in DdRT. After dialing in their SRT setups they said that they knew that their climbing would continue and their achey joints would get a rest.
 
Nobody has yet mentioned that Mrs. dDirt (sorry for the stuttering) climbing has the brakes applied to your rope all of the time you are ascending. To a very significant degree. With SRT there's no brakes being applied, for the energy conservation/usage win. I'll leave the math to the eager type students; it's been presented before. about 40% more energy used, lost to skidding the rope.

Not saying a long lanyard / short climb line doesn't have it place where it shines.
 
To me that is the added co$t of conversion from 1:1 to 2:1/transmission gearbox .
>>where you get the work done + cost of inefficiency as tax of usage.
Note that tho the efficiency drops below potential of 2x to 1.65 etc.
>>the 2:1 remains in the distance pulled as input vs. work distance output(thus the inefficiency).
If that is the only way to put the work into powerband; that then would be path.
>>but is more overall efficient w/o that overhead of transmission gearbox .
>>as is more than 50% if the effort for 2x more duration (of distance or time) , so more total 'watts' needed.
Look for co$t of conversion/tax at EVERY conversion.
