I like Diplock shapes and it looks a good board, the extra fin options enable you to mix and match beyond a single fin ito other configurations.
Good progressive board to hone your skills on:
BTW check well before you go anywhere which airlines are longboard friendly
Most good surf destinations have a good range of hire boards from the saggy mess to just under new quality
Have a look at Torq longboards too very well liked forum members. The UK prices for new are pretty much what you are looking at for the two boards you have shown
just couple of small considerations. PU = polyurethane foam standard resin glassing is slightly heavier than and easier to ding through to the foam than Epoxy Expanded polystyrene =EPS which is lighter and less water damagable but always needs epoxy resin for repairs ( or it dissolves)
See what you think, Look at the PU board if you see browning of the foam or shrinking around the stringers = water damage heavier still.
Both boards look pretty clean.
