tbh, i was super lucky last weekend. I had snapped my giant Reign X, so that was in the shop on warranty, and my mate had to work last weekend, so i managed to borrow his 2010 giant glory (Fully pimped, imcluding every bolt had been replaced with Ti). Rode that all day and it was suuuuch a sweet ride.
I highly recommend you borrow a bike or get a demo before purchasing.
BTW, what’s your riding style? If it’s more of a ‘plough’ style, then get something with a linkage, i.e. giant glory, demo, v10 etc. If it’s more of a smooth riding style, then start to think about single pivots, i.e. 224, commencal supreme, TR450, nukeproof scalp etc.
