From someone who's owned multiples of both. This is my opinion.
1) 15. Hot out of the wrapper. After 200 BP hits with 40/325 classic Ms the bat was the single hottest "Asa only" bat I've ever swung.
2) J3. No denying it's a hot bat. The bat that all new stamps are compared to. Perfect amount of flex/endload. Had a major production issue early on with premature paint cracks. Broke 2 in 1 tourney. Also the hype between graffiti and bubble was a little dumb.
3) J4. Also took about 200 hits to reach peak performance. Swung it in a league that used 44/375 and it killed the ball. Ultimately I put it down for an OG Cluggy which was right up there with 1) in performance but not durability.
4) new OG Juggy. Not enough swings to say.
J3A>16>15>14. I was not a fan of the 14 Juggy and didn't like it. The 15 is a great bat and after some BP is a great bat. I love my 16 Juggy it's crushing the ball. Are league recently switched to 52/300 and it hit them great and it also handles the 44/375 we hit for tournaments. My 16 has about 400 hits and keeps performing great.
What didn't you like about the 14?
For some reason never got a good feel for it. My teammate still has one and I cannot seem to hit with that bat. I swing My OG juggy or 16 and hit just fine. That 14 just can't find the SS.
Hmmm....I guess I've only tried the 14 but it (for me) has a huge sweet spot. Doesn't have the endload I would like but when it gets warm out it just seems to get better. I put down the future for the juggy when the temps get up.
J3A 26oz/27oz > 14 > 15
14 > 15 > J3A 28oz
I have a 27oz senior juggy n love the feel and weight of the endload, my question is if i get a the 16' juggy og in 27 are they gonna have the same feel? Also we hit the dudley synthetic 52/300's which are terrible they soften up wayyy to much. Am i better off getting the 16 flipper or get the juggy?
Hit my 16 juggy for the first time tonight. Wow, just wow. Hit one out second at bat and then switched to hitting lefty after we were out of homers. Accidently hit one out lefty. If it keeps it up it will get swings over my j3a.
