Hi Clay S,
Maggard, Connaughtshaving all have the 98 as 27/65 and the 20102 at 28/60 or 59
It's the Italians I don't trust when it comes to precision or details, fashion, food yes, detailed info less do lol!
In another thread it was determined that the Pros loft seems to differ from 59-65, slight diameter differences exist as well, since they are measuring mounted knots. Probably manufacturing tolerences. My Pro 10098s are about 61-63mm loft. I rather knots be slightly off than them trimming them to a precise length though. I have vintage boars like that. They don't split. I've blow-dried, hydrogen peroxided, bleached, boiled, scrubbed, etc. No luck. About to go shower-scrub with one.
