Of course, if you are lucky youve got a beloved "groundie" ready to undo the anchor once you are up there!!

Anchor? Not sure what you mean.

oh sorry, i lost the plot. your initial post implies you are anchoring the rope on itself. you could alternately anchor it to the ground, which would be the way to go if you had branches in the middle.

One small warning: if you anchor one end of your line at ground level and climb SRT on the other end, the laws of physics show that you double the amount of weight on the limb.

It works like this -- if you weigh 100 pounds and climb DRT from a limb, you are putting 100 pounds of weight on the limb. If you weigh 100 pounds and climb SRT with the rope cinched up tight against the limb with either a running bowline (not recommended by some climbing professionals) or with spare carabiners or a delta _link_, you are still putting 100 pounds of weight on the limb.

But, if you run the rope over the limb and back to an anchor point on the ground and then climb on the other end of the rope, you are putting 200 pounds of weight (100 from the climbing side and 100 from the anchor side) on the limb.

Personally, I use that method only on my initial entry into the tree and only if the limb supporting the rope is very big (in fact, I prefer to have the rope running through the main crotch if possible).

Remember, gravity always wins!

The weight on the limb in SRT or DdRT doesn't change but the load does. Small difference

WB,

Do you have a problem with working/climbing on SRT with the rope anchored at the ground because of the doubling of the load?

Terribly sorry, old chap --

I stand corrected; instead of doubling the weight on the limb from 100 pounds to 200 pounds, I have simply added another 100-pound load to the system...! Picky, picky, picky.

Okay, that's enough fun with you, Tom. In a few minutes I'm headed down to my practice tree to try out some new stuff that came to me in the middle of the night. I'd tell everybody what it is, but it might turn out to be so stupid that I'd rather nobody knew about it until I can prove it either useful or worthless. If it turns out to be useful I likely will brag about it at a later date; if worthless, there will be no additional posts regarding the subject...!
