My dad's sled (97sx7) is set up almost identical to mine as track/suspension/engine/pipes with the exception of clutching ...he's running a maxxuim/mpi roller. I've got a multi angle. I can say without doubt his clutching makes the sled more fun to ride than mine. Kind of a crossover type setup 50/50 on off trail. Both mild angles for flatland off trail. I really like the instant back shift. Was about to order an mip setup sometime later in the season last year and they had sold out of every helix they had in stock for the clutch. I've done a fair amount of reading up on these things, really to be no middle ground... People love them or hate them. Few different designs on these that vary from one manufacture to another, all seem to achieve same results. Swap out for the team, Bolt up and go on the mpi, machine work for the hauck ect... ect... but you get to use the conventional type Yamaha helixes you prob already have which is a plus for many on the hauck.
