I demo’ed the Orange 5 and Pace 405 last year back to back and found them both excellent. TBH i’d have happily bought either, but went for the Pace in the end as I got a better deal on an ex-demo frame.
The 405 definately has a more compact geometry, and was definately the better climber with the full-floater shock set-up, and accelerates really well as you’ll know. The Five was an absolute blast going downhill, but less sprightly and more of a cruiser then the 405, but a great all-rounder. It’ll probably give you the stability you’re after.
Both great bikes, i’d have really liked to have taken both home! :D
