Exactly what type - size/brand - of "rope snap" do I want to buy to clip my climbing line to my saddle? [
Many here have more experience than I and have already offered suggestions, but I will offer a few too.
If you are using ropes with eye splices, you probably want carabiners, not snaps. I would recommend the Petzl ball lock, more on that later...
What is best knot to tie the climbing line to the snap?
Either Buntline or Anchor hitch. Tie it every time you use the equipment, don't trust that it will stay tight from day to day or week to week. The TA for my tree climbing class at Purdue found that out the hard way.... Was lucky, wasn't hurt but for a few bruises on his body and pride....
I plan on buying a split-tail that is already spliced. Any specific suggestions as to length/strand/brand?
Get one that is similiar in make to your climbing line, but a different color. Differening colors make it (at a minimum) easier to distinguish it from the climbing line if both are in the rope bag....
Exactly what type carabiner to connect the spliced end of the split-tail to my saddle?
As I said before, I would recommend the Petzl ball lock. Easy to work, you don't need to pull/push anything in a direction you don't want to. If you aren't sure about what you want, order several different ones, and decide which one you like. The others can then be used for rigging/backup/decorations....
Do I need to place a "thimble" in any part of the system?
Probably not, but I'll bow to the bigger heads on this one.
Any other advice/thoughts?
Was playing around with Dad's new stuff on Wednesday night. I didn't realize how much I missed being in the saddle....
Get an ankle ascender. It beats the h*ll out of air humping. Use it when SRT.
If you have a new rope, break it in on the ground before you try to climb with it. I had to take an extra wrap with the Blakes to get it to hold. Then, as the 6' section of rope I was using got broken in, the Blakes locked up so tight I couldn't come down on it.
ALWAYS carry more than one slickline and wieght. Nothing sucks worse than having to climb the tree 15' at a time because you got the throwline stuck 50' up in a crotch.
Get a descending device like a rescue 8 descender or the Petzl ID. It will save a lot of heat on the split tail and the climbing line and they will last longer. The ID took a little time to figure out the other night. Not sure if it was because of the new rope or whether I wasn't using it quite right, but it took a little time to find the right spot to come down on it at a reasonable speed. Other than that, I liked it, but an 8 would do the trick as well.
Personally, the only place I liked rope snaps was on my safety lanyard. All connections to the climbing line were with 'biners. I think the snaps were easier to use with gloves on, and I moved my lanyard(s) around a lot more than the 'biners on the climbing line. That brings up another point. Keep an extra lanyard in the truck or on your saddle. I can remember needing to be
triple-crotched (the climbing line above, a lanyard pulling me sideways, and one pulling me closer to the tree) for one cut and I couldn't have done it without the second lanyard.
And if you don't already have it, spend the $15 and get a copy of the Tree Climbers Companion!
This was a little long-winded, but I hope it helps...
