Well i like them all for different outfits. Right now the dirty gray BBS are faves as well as all black RO Ramones. Have seen some ridiculously stiff orange augustas at archive but they were more of a miss design wise..
I just lean towards the bulkier shape of A1923; especially w/ a taller shaft. The IS boot just seems too clean to me- almost m.a+ like. I guess just preference really. The 2 IS boots I've owned sat on the shelf "new" for months...
/\ I see your point. It does come down to a personal preference. That's basically what @Synthese rightfully said a few posts back.
I wore mine the moment I could
The sole on the IS feels really solid, more so than any other I have used in recent memory. The A1923 derbies from SS09 is the only pair I can think of that had a sole that wore out slower.
