New Board advice for long to short transition

I have been surfing on a longboard since the age of 12 but never as regularally as i would have like coz i live on the otherside of the uk to the good surf (by uk standards). Now i have been able to start spending some a lot more time on the board and on a more regular basis.
Now i want to make the leap to buying a shortboard but i was looking for some advice about what type of board, what size etc. would be best. I'm 180lbs (12.5-13 stone / 82kg), im 6ft 2in and im looking for a board thats gonna make the transition easier. i generally surf fairly rough conditions but im also looking it to take the board with me to other great surf spots.
So im looking for a shortboard thats fast and fairly stable and have enough manvourability for the big carves on waist to head high surf but that can still work wonders on bigger surf.
I personally like the sound of fishes especially the channel islands fishcuit, is that a good idea or am i completely deluded.
Looking for some advice so please reply coz i want to get this board as soons as possible so i can get surfing
