If it was my bike, I would choose option #2, oem rod, replate cylinder, and wiseco piston.

+1 on Luke's. He stands behind his work, and you will LOVE the 444 kit. As far as a rod, stay away from Vesrah. Put one in my 444, and it lasted 5.2 hours before it failed. Classic fatigue failure starting from a micro-crack int e rod. Called and e-mailed Vesrah asking about warranty, and never heard anything back from them.
