I'd be very sus on it if you want a strong board. I can't vouch for the Guerilla but other F2 waveboards have been very lightly built. The single sandwich on the Maui Projects was very ordinary compared to RRD, starboard etc double sandwich construction. They were no better than a freeride board construction-wise. The old 1998-2003ish age yellow waveboards (the one swith outer skin of ASA like BiC make) were moulded with beanbag balls poured in and then steam pumped thru to semi melt the balls into something resembling "proper" stryo. Needless to say the cores of those were weak.
I know the new boards may be quite different now but the Maui Projects were not long ago and when F2 write "carbon" and "sandwich" on the board there will not be much of either compared to some other brands.
A mate has one, and we spent one afternoon swapping boards and sails to see what the differences were. We found that it needed a good knot or two more wind to get planing than my flow, and was more bouncy when it did get going, probably due to the wider tail.
I'd get the JP if it was me, but that's just my uneducated opinion.
