I've been watching this thread since the beginning & sat & watched it unfold, partially outta entire disbelief that it even started.
you really need to look at the wider picture to compare, which I'll soon expand on
handling? its too subjective, its like clothing fit, what 1 person likes, another hates. so as much as I love FAT handling & think theres no special handling traits of konas (or indeed build features of their frames), I'm wise enough to accept that others may get on better with a kona than a FAT (Jez prefering the higher front end for example). blondes & brunettes, personal preference thing..
while a TET kona might be better built than a MASS steel. or a saratoga steel (really a serotta unless its a BOI fork or all steel shockabilly as they were the only things actually built by ingelheart in this period) is better built than a MASS steel... this is TOO finer detail. (although yes I agree, serotta both steel & ti were better built than Mass Fat, truth be known)
the wider picture in simple terms:
the vast majority of konas were mass produced in taiwan (the percentage of TET built & other custom konas is absolutely minute as a percentage of all konas built)
the vast majority of FATs, (were firstly considerably less in number than kona), were built with waay more quality control & the percentage of custom builds is waay higher.
yes theres examples of both konas & Fats breaking & Fats can have a rust issue if not maintained. but as a simple general rule that always applies, smaller scale production runs with a higher percentage of custom builds will always be built & finished to a higher quality than vast mass production (with a tiny percentage of custom). this applies in nearly all aspects of life & not just bikes.
yes mass production is catching up & will doubtless someday be able to match low production near custom runs & yes to the untrained eye a bare steve potts & a bare kona look very similiar. but for every 5000 people who cant see whats wrong with their kona, theres 50 who can fully appreciate the potts, FAT, serotta or whatever.
doubtless this thread will run & run as people are always massively passionate about their choice of bikes & defend them to the hilt- which is a good thing!
the FAT lovers will agree, the kona lovers will disagree. its like the disc brakes Vs sh,te road calipers, fully rigid over 160mm travel arguments & all internet arguments in general
normally i'd just turn a blind eye... but to the FAT chance lovers I actually miss FAT chance
so thought I'd chime in with my 2p regardless
