just wanted to weigh in with my own personal development -
I've now sewn up the uppers on my Komodos twice, and my Bikilas not at all.
I put the Komodos in Glasgow and the Bikilas in St Andrews; I split my time 50/50 between the two towns so they should wear at the same pace.
Verdict: soles are equal; uppers on Bikilas are sewn such that if you're going to abuse them with vegetation, choose Bikilas.
(but I'm still drooling over Spyridons. Have you tried them yet?)
