I took a Freak30 26oz out of the wrapper and hit it indoors with a mix of balls, from classic plus and there was one stadium in the bucket. I am more of a base hitter but my buddy I was hitting with is a power guy and played local B USSSA here for a while. After about 15 swings from each of us it had a small glue rattle. Balls were already coming off well and at around 80 swings it developed a small paint crack. I hit it probably another 40 times indoors with some good balls two days later and at that point it sounded like a maraca. I figured since it had maybe 120 swings or so, I would send it in and get another with a return, which Miken was cool enough to do. I would assume at about 100 swings it would be close to testing around 220. Note I did not say "failing" because for some reason, they lowered the pass/fail threshold to 210 for north Texas. Tourney ball here is all USSSA and we hit classic plus balls. I would assume the F30 should last a while with classic plus balls. As far as harder/better balls, the durability is not there. The F12 seems to hold up to harder balls and colder weather IMO. We have a local USSSA league that uses Thunder ZNs and most nights over winter it was <40 degrees and the F12 held up great, still no rattle or paint cracks at all.
