Yeah – I must admit, I rode a Roscoe 2 when they first came out, loved it, and I ride a Five normally.
I'd say build it lighter (new wheels and tyres) and ride it harder, for everything. It's all the bike most people will ever need!
The 2 were a comparable weight (my five a tad lighter with Floats and less bombproof wheels), solid as anything (had the Talas 32's on with QR15) and I rode faster on it on my first ride than I had ridden the Five for a while, up and down Dartmoor! very confidence inspiring.
Jumps like a beast too!
My only complaint – it creaked!
I could've bought the demo bike for a very, very reasonable price, and would swap the Five for it, if…there wasn't the issue with the forks, which a) makes changing it a mare, and b) makes the bike impossible to split and sell on, which knocks the re-sale value.
