I'm looking and researching too Travis. I did the hard way through MTC which is somewhat local (so I paid tax, even worse) and bought the billet hub, single stage lockup, all brand new. Ran half a season experimenting with a not so great turbo tune and spring only and a shock that was fucked. I tried different springs in the clutch, actually went too far and cooked a set of plates n fibers in one pass once. Everybody is upgrading right now so the used stuff, MTC multis and what not are out there and affordable. When you go to a gen 2 or hays, they don't use the same baskets so those guys sell the billet basket and clutch for half or less for what they paid. I see it as a journey. I am going to eliminate all problems, get the single stage where I understand it, then maybe find a used multi and I can use my same basket. Learn that. Then move on. Once you see how the setup is and look at the different clutches available, they aren't all that different in design.
From what I have learned at this point, I drive my single stage on street with the heavy springs. I go to track and pop off cover and put in some smaller springs and reduce static. Not too much. I have yet to do this season with new shock since my motor is still with builder till the end of week n then I need a tune and AMS set up. I need to get those solidified and running good before I alter the equation with a clutch mod. Fastest times from us guys that wont get as much seat time as the dudes that live right by the track is going to be a slider. It isn't streetable although the hays convertible can be set up that way. I have no clue how to set up a slider. I also hear negative things about Hays but there are guys who wouldn't sell theirs for anything,
