I can pull out an early 90s aluminum bat with the balls that were used at the time and all 170 lbs of me can hit pop fly after pop fly that clears a 300 foot fence if I wanted to. Give me one of today's bats and I can clear every fence on command in that category of 82% of regular season tournaments and 90 % of worlds.
I've given you my statistics, time for you to find your own. I think more interesting than field sizes would be how many DBOs do major teams hit compared to AA to A to B to C to D to E. I think what you will find is that the higher up you go the less DBOs you see due to the fact that the higher players have more bat control and ball placement.
The new complex was a former spring training facility (fields were already in existence) and also hosts tournaments other than slow pitch. The result is you need the biggest dimensions required for intended uses. The new complex does use temp fences outside of the MWS and HOF Dual.
Let me ask a question for you: Would you say statistically that playing with a wood bat on a 280 foot field would be the equivalent of playing with today's bats on a 325 foot field which is the same as playing with the green bell corps on a 300 foot field?
You also didn't answer my question on what you consider PEDs. Do you consider a senior player who uses prescribed testosterone replacement therapy so he can still get it up for his wife/gf but doesn't want to tell others about it that happens to play softball cheating?
