I have an Alptitude which I use for erm "work" in Lee and Cragg Quarry. Trail inspections etc. Its really is a very good bike climbs really well and goes down hill really well, fun on the pumptrack too (not that I can pump very well yet). Seems to be a good well sorted bike ideal for the rocky, bermy techy stuff I needed it for. I have been on a giant vt for the past few years so wasn't sure about going back to a hardtail but I'm glad I have, its lots of fun.
Can't fault the Alpitude really (apart from white grips and sadle?)not light but you don't really notice the weight when riding it. Not riden a P7 but know a couple of people who have them and they seem more than happy with them as well.
Sounds like you need a test ride!
