setpoint pulp costs is 139/72 vs tretorn 149/72, i don't mind the small cost difference either way and would get sp balls if they work well. do you experience any arm issues with sp balls ? how do they feel compared to pressured balls ? does the felt last ?
i have arm and shoulder issues, so a ball that's not hard and heavier than pressurized ball is preferred, also i checked the price, tretorn is 149 for 72 balls and trinity is 79 for 72 balls. it would be nice if trinity balls could last a year without losing its bounce and felt.
i definitely will get one when it's available because of its compact size, light weight and programmability. however at well above 1600 usd mark it's not affordable for many. i can see if it falls under 800usd it will become very popular.
