Hitman, please don't type in all-caps

I just learned how about 6 months ago. And have found that it's not so much about your hieght as it is personal preference. Sherrills sells a 12 foot piece of technora that you could experiment with because you can lengthen it or shorten it by tying your bends at diff. Lengths. Just don't cut it till you find what works best for you.
One more tid bit; remember practice on a doubled rope, put it through a friction saver so your ropes don't separate at your tie in. Ropes that separate when they cross over the limb you tied in on will tend to spread your hitch and it will cause sliding,and possibly a short fall. I think its called '5 to 1' or something like that.
Ok last one i promise, a throw bag hung at the bottom of the ropes about 8 inches offthe ground will help keep the ropes together and you will get better locks.
Ok i lied, the first time i went up, 4 mins 43 secs but now im consistently around 28 secs. Do it once a day and you'llbe under a minute in no time. In my practice tree the bell is at sixty feet, then when you go to a comp their bell is around 49 feet. I practice that way cause you still have some steam when you get to the bell at the comp.
