Fastforward to my Paradox, Highlander and Fuel Ex-e with 425mm and 440mm (both FS bikes) respectively, which is the same for all frame sizes and they all ride exceptionally well.
I sometimes wonder about the Paradox and longer stays but it's such a fun bike that the thought doesn't linger for long.
I'm loving longer stays on my FS bikes, but did not find the same on my Waltly hardtails. The first one had 427mm stays and was heaps of fun (but a bit demanding to ride as you had to be concious of keeping weight on the front tyre), the last one had 444mm stays and while it was 'easier' to ride (less fussy about bodyweight positioning), it sometimes felt a little 'dead'/unresponsive because of it. I think the "directness" works well with the shorter stays on hardtails, the instantaneousness is easier to predict somehow.
Hard to describe the actual sensation - best I can do is say that with the long stays each impact felt like three seperate bumps. With short stays it felt like front wheel absorbed with the fork, then back-wheel bumped and pedals got jolted pretty much in time with the rear wheel. With the long stays it was like - front wheel bump/absorb, then slight pedal jolt as the fork rolls off the back of the obstacle and rebounds, and
then the rear wheel hits and jolts the pedals again. A lot more subtle than that in practice obviously, and it wasn't hard to ride or anything like that - it was just a bit of a weird feel that I didn't enjoy compared to short CS hardtails. Maybe a flexier frame would hide it better, but the Waltlys were moderately firm (with a bit of springiness).
Basically those Paradoxes (V3's?) are freakishly good, you're not missing out on anything!
