I would pick the HRC from what you listed, the XR is only slightly larger than the stock EX. The Hot cams will be good improvements for the money but don't know how durable they are. Search ex riders for the specs, they are all listed there.

Hotcams is a reliable cam, my bros had his for about 6 months now with no prob, dont go with stage I though go with stage II, its a big torque increase from 3rd-4th and u hardly lose any bottom end
