I upgraded all of my mags to play against uncapped timmies around 2005/6, then lowered the rates on a couple to 15 bps, and now I'm building a plain classic-mag to have a mag slow enough to play under 13 bps without questions or a pump. My other classic does better than 14 bps (EP). With a little luck, I'll have this one hitting 10 bps regularly.
With HPA on most fields, weight is about the only possible complaint on a classic mag. You missed some fun but rather expensive RT play days.
You'll see a lot of pump players around here, and some damn nice pump markers, whatever your preference.
