22" Razor 4 blade (with 4 solid vent plugs) on 200 SHO....Hole shot is fine (about 4 seconds @ about 3000rpm). I'm happy with that but for curiosity I want to see what a BIT of venting might do. So, question is, can I just remove 2 plugs opposite each other or should I replace all 4 solid plugs with "small-hole" plugs? Thankyou
