I have personally studded over 20 sleds for myself & for others for $$$. Anywhere from 78 on an Indy Lite and up to 268 on my last Thundercat.
None, myself included, have EVER lost a stud or torn a track in the last 14 years. Using a template or my own patterns before there were templates. I have had studs broke off flush or bent almost 90º at the backer plate, but the track was fine.
I ONLY use Woody's, I pre-stretch the track (Ride it for 150 miles minimum w/o studs), use generous amounts of Loctite 271, use the PROPER length and quantity as recommended by Woody's, and use the PROPER drill bit and be sure to slightly "melt" the hole with the bit by holding it in the hole for a brief second.
I used to use a soldering iron and burn the track but my lungs are more valuable then a track. :unsure:
Lastly, if there is something I am unsure of I call Woody's and ask! They have always been very supportive.
For the record I will not ride w/o studs or with anyone else without them. Even with a 340cc sled. Safety is the deciding factor
I also do not work for WIEM (Woody's), I tried another brand ONCE...1/2 were snapped off in a season. And I won't use stainless studs either, to soft.
Nothing like the good 'ole Gold Digger for all around use. Should get 5-7,000 miles out of them if you don't ride to much early/late snirt.
