I have a Tusk clutch I havent had time to install yet,but someone else had one and said they liked it and you cant beat the price.It seems Rick said he liked the stock friction plates if I remember right,but Im sure everyone has a differnt answer.But steel vs aluminum,I think everyone will agree with steel.Way less tranny oil contamination,better wear/life (although I managed to make my stock ones last a long time) and with steel you get a little bit of added flywheel weight effect.
