I don't know if there's any tables, but the early S17's were definitely soft, usually by 10 flex or so. Back when I was using 75 flex, I had my eye on an 85 Drury S17 on "clearance" (still $150 last year, ugh), felt in that same neighborhood.
I know with S19's they stiffened back up to the actual rating. There may have been some later model S17's that were a little stiffer, can't remember.
Hyster, were you comparing to a Supreme stick or Vapor?
What I am referring to is Easton has the listed flex being what the stick will be after you cut a couple inches off of it. So an uncut 85 flex really is closer to a 79 and then when you cut it down to the 85 line, it is an 85. My question was just what the listed flex is on an uncut 100 flex Easton stick.
