I too chose D&D's (Pensacola, FL) kit. They used to do the sleeve kit but decided the boring and re-nickeling was the better alternative. Their opinion is that the non sleeved version would far out last the steel sleeve version. They have already redone previous full Wiseco versions.
I went with the regular Wiseco pistons as opposed to the high compression version. I also tried the lighter flywheel and had them put the original back on. The lighter flywheel gives the bike more hp at higher rpms, but took some bottom end torque away. My primary goal was to get the most torque and power I could in the mid range rpms. Either D&D or the full Wiseco kit will make a huge difference in the bike performance. The bike now has all the power I could ever want. It's rides 2-up with a lot more oomph than solo before.
As stated above, they are my closest dealer (40 miles), they do an incredible job with their race bikes, they have their own dyno, and I really trust their service dept. The chief mechanic is the owner. BTW, his son, Rob McLendon, is the leading Thruxton Cup racer the last two years and is now racing a Triumph sponsored 675.
