Fourth boards

Hi all, i am thinking of buying a shortboard, im going from a 6ft 10 fish, but will still be using this, i want the shortboard to progress onto, and for bigger waves were fast bottom turns are priority, i would prefer a board that is good performance from 2 to 6ft waves.
At the min it is between the fourth doofer and stoker, also had a look at an ABC custard mustard today which is much cheaper, any used boards i looked at are pretty dinged.
Im surfing mainly ireland beach breaks, but would like soon to try easier reefs in nice conditions, any help would be appreciated cheers
