In the long term do you ride in the wet much? From what you said in op I would be led to think not.But if you do then eventually I would lean more towards pr2/3 as its a better alround tyre. Don't worry to much about grip, I have used the pr2 and 3 on track days and never had a problem with grip wet or dry. Though in the wet it will give you enough feed back to tell you your being a tool :P
