I put 96 in my prox600 since it is all I need.I used to run anywere between 192 to 144 on my other sleds but I noticed a drop in top speed with all the extra weight in the track.You won't win any short drags against sleds with more studds if you are on hard packed trails but in loose snow there won't be any diff.Also you won't need the expensive 8 or 10 inch carbides on the front to turn the thing.I perfer this setup because I like the backend just a bit loose for powersliding corners.
Also use a pattern that has as many scratch lines as posible and place them close to the rails as there is less support at the very center of the track.I us a long V pattern that covers about 12 pitches for the least amount of repetition in my Pattern.If you have a good pattern you will hook up like you have more studds then you do.
Use a piece of paper to experiment with designs when you come up with one that looks good use it.
I have a 2001 with 0.91" lug and I run 1.25" with no problem ever in 2000 miles. My dad has a 2002 with the 1.25" lug track and he went and bought 1.625" studs! I thought he was crazy to put that long of a stud in. Well, I put them in and he hasn't had any problems either. We just got back from the U.P. last week. The 1.25" tracks have thicker rubber between the windows for more tunnel protection. They sure put a lot more room in there than the older sleds too.
I would go with 144 on that machine. The standard trail pattern works fine. Usually that means every other lug is studded on the outside edge of the track. This gives the best control. I've studded all my 600's this way and never ripped a single window. If you have 1" lugs you could go as high as 1.25", but I would go one less. I know woody's has a 1.075 and stud-boy has a 1.080. That way you still have good penetration with a little less stress on the track. I like the stainless as well. Good luck.
You want more than .075 or .080 penetration. I say go with the 1.25" anyway. Just don't put them too close to the windows and you will be fine. I've put 2000 miles on my 2001 and have done a lot of drag racing with my buddies and have never ripped out a stud.
