What clutch should I get?

My clutch is going out and I'm gonna replace it I just don't know if I should just stick with a stock clutch or if I should get a beefier one. I have 35' Toyos on 18's with a 6 inch lift and just geared down to 4:88. What would be the best style clutch for me?

 

I was checking out some URD clutches last night but I don't know what would serve me best. What's the advantages and disadvantages of stage 2 compared to the stage 3? I just thought that the more stges you went up in a clutch the more power your engine was putting out. If so all I I've is a K&N intake and magnaflow dual exaust so I'm not outing out much more than stock. Is there a good type of off roading clutch for Tacomas?
