How tall are you? If 6:2 I would think XL would be better as RM are sized a little smaller than some. Depends if you like a long bike or a shorter one I guess.
I really like it, if you want a bike that feels like a bike it is definitely the best of the non fazua bikes that I have ridden. I still feel the weight when trying to lift the front end etc but I am rubbish at that sort of thing anyway so it might just be me!
If you want a bike to roll over...
I think it is a really personal decision. If you really have no hills then for me it would not be worth it. If you have gentle hills and some fun trails it might be an idea. What type of mountain bikes do locals ride? Cross country hard tails, short travel full suspension or longer travel enduro...
