Hi Pro, Do you think the hack saw would need extrovert driver's and what stud's, 1.25" or 1.375/1.40"? Can i get the 1.40's to stand with good backer's or will they lay down? I was thinking 1" track with 1.40's wouldn't be a bad combo for trail and hard pack drag racing, I have an Attak so i would go with about 212 stud's center and out side belt's. I studded the out side belt's last winter and it made a huge difference on hook but ratcheting became a problem. The track as tight as i had to run it could not have helped power to the ground and it was still ratcheting any way. I noticed all the lake racer's running 1" track's and even as loose as the slop got at cable the 1" track's were still the choice, Seams it all comes down to stud's (chisel's when getting serious). kviper
