I want to stud my friends 1.375 track F-7 and I was wondering how many studs to put in it and what pattern. I was thinking about going with 153 1.450 Woody's Mega-bites with 7° angled backers. Can I stud on the outside? Will the angled backers be OK with this long of a stud? He weighs 260 lbs. so he will be working it pretty good. Do I need to keep them out of the middle of the track?
