Swiftacular

Hey people, completely new to trials/street, and just acquired a bike especially for this purpose. Have quick question about wheels though. The bike came with Leaf Rims on NPJ hubs (36h), but i also have some Spank (subrosa?? ill have to check again) 32h rims. Are the leaf wheels that good, or should i really go with my instinct and build up the spanks, and flog the Leafs? Thanks in advance.
