straight and the preform 
simply wraps around it!? 

    Yes. Use the crossover mark closest to the end loop to start wrapping 
them. 

    Finish the short leg first - it'll make wrapping the other leg easier. 

    They are meant to be put on by hand but I use a medium blade screwdriver 
to finish the second leg by putting it under the strands and working them in 
the wrap direction.

[I know, like a Chinese finger lock that the more you pull the more they 
"grip"...BUT]

    But what? I've never heard of one pulling out, not even after a tree has 
fallen on the guy. (The grip moved less than an inch in that case but didn't 
pull out.)

thimbles (i have the right size 
thimbles) as well as around insulators?

    Yes. Use the second crossover mark (farthest from the termination loop) 
when you use insulators, otherwise the termination angle is too sharp. 

    You're allowed to remove the grip twice during installation without 
compromising the holding power. Any more than that and you start losing the 
grit 
inside the grip which provides about 40% of the holding power.
