HS player is using 2018 33/30 Easton Hybrid. Loves it. Still takes BP with a wooden bat, as he has for years now.
14U player started out using a two piece Louisville 718 -5 USA bat, but has dropped it for his brother's old 2016 32/29 Velo. He likes the balance a lot more, and seems to be hitting better with it. Ball seems to be faster off the bat, and there doesn't seem to be any less distance. He also likes the feedback of the one piece metal. The USA -5's aren't very popular. Most kids have them, but are using a BBCOR instead.
Just finished talking to my Senior HS'er, and he said he's never been so happy with his bat situation. He's had a(BBCOR) 2015 Easton S1, 2016 Velo, Easton Z core (two), and finally a Easton Hybrid. Uses his Louisville wood as much as he can in practice and wooden bat tournaments. Is looking forward to using Sambats in college...they have a very good rep.
14U just hit a triple 325' on the fly up here in the cooler air of the upper midwest with the Velo referenced above. I can't see him hitting any further unless it gets hot and humid...he's 145 lbs. soaking wet. I was going to buy a new Velo, which is supposed to be more or less the same as a 2016, but at this point I don't think I would be able to get him to swing it. The Louisville drop 5 USA bat is just gathering dust at this point.
