I am wondering what to do i have the sp 1.375 track but I don't think I really need it. I am thinking of getting a shorter track lug so I am holding off on studding my sled until I make up my mind on what to do. I am thinking of getting the hacksaw or the ripsaw. I do like to have the occasional lake race and I Don't really want any restrictions from my track slowing me down. I have seen 107 on gps almost always on the lake thin snow(crusty) and as low as 102 gps with a little snow cover but it feels like it can do a little more the fastest I have seen was 109 perfect conditions on gps but my speedo was saying 116 so there is some track spin. My question is if I get a diff track im not sure if i can install it has dd i never did it before and is it worth it for me to get it I'm sure i can do it though , what track to get what improvement in top end would i see from the ripsaw over the 1.375 our should i get the hack saw if i do get either one of these tracks i am going to stud it. the hacksaw is 1inch and the ripsaw is 1.25 but the weights on these 2 tracks is much less than my stock 1.375. sorry if this is confusing, any input would help.
