Here in the Islands, Senior league 60 and over, is played using debeer pn14s, 14" softballs, with any senior stamped bat, including those og ultras. Fences in annual senior state tournament is set at 250'. On Oahu, Upper Divisions play on 300' fields.
(Majority of upper divisions) would rather play 300' fields with 12" 44cor/375 comp balls but as of now if you want to play senior softball you play with 14" balls.(60 and over)
All you seniors that play leagues using 12"/375 balls are truly blessed. sigh!
So all you players that complain about senior bats/balls being too hot and risk of serious injuries, there it is, PLAN B! It is what it is haha.
All I ask for is a little sympathy
