I look in the mirror because I can't see down very well, (eye injury). I think I hit a bit lower than most because I dont have much meat on my ass. I know I move to much, but it doesn't hurt and I have not bruised so who cares! I'm using up left over 22 x 1" pins, and have 22 x 1.5" for when I get more meat on my ass.
The first time I hit a vein, my gf stuck me. I felt a bit of a sting when it went in, but not when I stuck myself last night.
Thanks for everyones input....
