Yeah binocs are good--they should be used a lot more, and bigshots a bit less. final thought is to aim lower when you are in doubt, for the sake of the tree. I've seen way too much collateral damage done by throwballs and bounce tests. This decay-prone species now has a 10" gash in the very crown. :bang: Attached is a pic of the tiny codom that split--2 1/4" at the widest point. The branch above the fork is 1 1/2" wide.What happened was the 3" co-dominant crotch split and one side gave way completely, later I found a 10" tear through green but coarse grained wood. So, for me, no more 3" TIPS in water oaks... I've used 3" TIPS in white oaks lots of times without a problem.
I have tied into some small stuff in my time, but never that tiny!
The good training for my newbie nephew was much more important than the gash, but the experience reaffirms my (and, I expect, his) skepticism about gear usage. Just ask my wife--I like to KISS.
