There are different points of view on this. My only experience with studding is to make sure you don't under-stud the track; if you do, you may throw studs and bend them, as well. You're talking big money to replace and re-stud. With 96 studs, I threw two studs on my last 2000 ZR440 (96 hp motor) and bent about 15 the first week out. I immediately went to 144 and never had a problem again. I put 156 on my F7 without a second thought. Happy I did.
