I bought a Lib Tech Puddle Jumper in January 2019 as a travel board and it ended up being the only board I rode for an entire year. I used it in pretty much every condition from knee high slop to big bumpy point breaks and draining OH river mouth barrels. I definitely found it's limits but I'm still impressed by what it can handle. I have the 5'5 30.5L and find it's the perfect dims for me at 5'11/170 x boardshorts all the way up to 6/5 fullsuit. Duck dives insane.
It paddles great and lets me catch waves that I shouldn't be able to catch. Glides really well once up, I'll often just cruise on it when the waves are really small and gutless, or on sections that back off. The wide nose and decent amount of foam up front lets me pump once or twice and then just move forward on the board and try to throw a cheater five or goof around without bogging down too badly. It can handle late drops in better waves if you really stomp on the back to keep the nose up, if not there's not much flip in the nose and it can get caught in those tighter transitions. I also felt the width of the tail getting in the way in really hollow conditions, but I was just pushing the board past what it/I could handle at that point. The speed you can generate with the board is awesome in smaller or softer conditions, once it gets bigger or more powerful and you don't have to generate your speed, controlling it becomes an issue. When you're going so fast (like OLO speed... swear I've hit some speed records on this) it gets pretty skatey, really skimming over the wave, and with the wide tail and short rail line it gets hard to push it over and put it on rail, at least for me.
I've been running it with the MR twin + trailer and also the PC-7 in quad and thruster setup. The MR twin + trailer works really well, lots of drive and fast, but I feel it can get kind of tracky, definitely feel like I'm doing more drawn out turns with it than with the PC-7 in quad setup. Don't remember what running it without the trailer was like, I should probably try that again. The PC-7s in quad has a bit less drive than the MR but I feel like I can get a bit more vertical with them. If I push the tail in turns I can blow the fins out. My first few sessions I used the PC-7s in thruster set up and it went well in bigger wave. I tried that setup again recently and found I could feel that third fin dragging and less speed overall compared to the quad and twin + trailer. Haven't really tried moving the fins around in the fin boxes yet, I always set them at the same spot, but you can definitely move them around in there. Twin tabs have maybe half an inch of adjustment, FCS2 have maybe an eight?
I love the construction and durability. Don't know when the board was built but probably 2018-2019. I got two small dings on the rail near the nose (very stupid smashing the same sharp rock twice incident) and havent fixed them and can't even tell they are there. Second stupid incident, kicking out last second before shore pound, ditched my board, felt leash go slack, thought my leash broke, pulled it, board was being held underwater, shot out tail first at my face. Fins hit me square in the nose/bridge. Chipped the fin and pushed it partially out of the box. Fin box was fine. Face was like fin.
In comparison, I bought a Ghost in February, standard glassing schedule, and I had more dents in the deck after three sessions than the Lib Tech after a year. Traveling the Ghost got pipe insulation on the rails, some bubble wrap on the bottom, in a day bag inside a double board bag. The Lib Tech got a towel thrown on it in the bag.
Feel wise I can't say much. Doesn't feel chattery or dead or have weird flex. But it's only 5'5 and honestly I'm not sure I could feel the difference in flex patterns of different constructions in that size.
My buddy just ordered a Lib Tech PJHP, with the Futures compatible boxes, looking forward to comparing the two.
Overall it's a super fun board. Great one board quiver for shittier waves we get here.
