eeeek fattys on a leeson, look mingin :) whatya want is some pashleys(or identity tuning forks if you need disk mounts!) they will compliment your frame well!as well as being very good (Y)
as for cranks, burns and tensiles are very good, but im not a fan of their looks, unfortunately you are a bit restricted when it comes to bbs, cos you have to get clive to fit a new'un if you dont have the correct interface fitted(square or splined)-which is alot of time and hassle
personally i think the raceface lp cranks look pretty cool, and are good too, but i guess you cant beat middleburns over all quality and service+backup when things go pearshaped, if its possible go for 3 piece-i cant belive how much better mine feel over alloy cranks (Y)
