I will have to say that in the last 2 months, I have climbed DRT once, and looking back with what I have learned now? I could have done that job SRT.
it is truly a revolutionary tool that belongs in every climber's (who does more than spur/flipline-removals and "prunes") toolbox.
It creates a more in-tune, intelligent style of climbing.
I find myself:
A) planning my climb more thoughtfully and intuitively from the ground. IE. more re-directs = less limbwalks
B) climbing the tree more, which is just like being a kid again, except you are tied in from above, I think this also helps your climbing mind and body.
C) I clip a revolver in up high when I have to do a lot of up and down, this creates a sweet 3:1 MA and this is much more efficient that body thrusting all the time .
D) and finally, my pure climbing strength has improved, SRT is a bit harder to move short distances in if you don't want to clip into the pantin, it does take some gorilla-power; which has improved a lot since I started SRT with the RW. I do notice that when I do try DRT here at home to see if I miss it, it seems very easy, but very slow, cumbersome and a waste of time and energy
Best of all, the ability to not have to isolate a TIP is the shite.
As long as it is over a couple of limbs or crotches, even if it is spread out, will be good for climbing on, and even better is watching that line come out slick as sour owl-poop after weaving a spider-web through the tree

no more stuck friction saver or pulley-saver.
I think DRT will always have it's place and is an awesome system for a lot of situations, but I have been finding more and more that it is not THE only way to effectively work a tree.
Especially with my style of work, and my niche' , which is no boom-truck, working in tight areas and a "tree-care" specialist, not a removal specialist. I do them when I have to, but I would rather not, remove it, that is the last time you will work on it...

ya know?
A couple of things I would like to see on the ZK-1 2.0:
1) smaller
2) mid-line attachable as a factory build, not a modification.
3) aluminum frame or a lighter vented metal frame with rounded , flared edges, if alloy, maybe a sweet colour
this would be the ultimate SRT fashion accessory for all us converts !
Kudos to Kevin Bingham and Zack Kenner and Luke a co. at treestuff.com for making the 1st versions available, although I see that the other big 2 are carrying them too now .
cheers, and climber smarter, not harder
