got a Soul and an Alpine.
I also considered the BFe mainly due to it being longer in the TT than my alpine (I bought a 15/21 Alpine) but after asking on here, I lightend the Soul (replaced the Pikes with some 120mm Rebas) and built the Alpine burly with 2.5" High rollers and a 66SL fork.
The alpine is a VERY capable bike that appears to get better the faster you go.
TBH either the BFE, Alpine or others seem to be very good.
I use my Alpine for 2 hours blasts round Rivvy etc. with big sticky tyres and a weight of 32lbs it's considerably harder on the legs than the Soul, but is good fun.
Be honest with yourself about what you are going to use it for, if it's for a play bike that you can pedal then a BFe or Alpine etc will be ideal.
The big bit of advice I was given was to make it different from the Soul.
