Thanks for the replies guys... Ive always been a fan of how monty's have felt under my feet and looking at my current ride, the geometry doesn't seem too dissimilar to the the m5. Even so, I think a slight change in geo wouldn't make much difference to me at all. I've ridden so many different bikes over the years from 26 to 24 to 20 street, comp style, bmx haha so I'm not gonna freak out too much. It isn't uncommon for me to slip off of an edge and catch a stay, but most definitely don't hammer them like i used to.. I'm much more reserved nowadays regarding side hops UPs etc, its not likely that it will see much damage at all to be fair. Ok, I think I've convinced myself to get an m5, they look pretty awesome and if carbon has come as far as you've said ill have no trouble.
@Mark W your insight into the new OS model has been helpful thanks for shedding some light on the design changes and benefits for me!
