I had a set of FR5s just last year before selling them for an upgrade. Great set of alu wheels. Not sure with your budget if you could possibly make a wrong decision, barring the Mavics. Although, I'd certainly lean towards the lighter ones for your climbing tastes. I'm sure you're looking for more substantial information here, but what I can say is that the FR5 spokes were a reason I ended up selling before one actually broke; they're expensive to replace.
