Not sure if it helps but I’ve heard lots of good things about canyon bikes and was able to throw my leg over one for a par park bounce once, it felt very nice (was their FR bike). Not sure how you test one.
Another for the mix, how about one of the new ragley FS bikes? The 100m travel one looks ace and would be great for Surrey Hills if it lives up to the hype.
I wonder why the Orange 5 is such a divider of opinion? I mean loads of people swear by them, and then lots of other people hate them. Strange? I have found that shock tune is very important, makes all the difference. Personnaly the only bike I would buy is a new 5, odd.
