Small wave board?

[garbarrage]

Having fallen out with longboards due to a prolonged though enjoyable time on them ruining my short-boarding abilities for a while and getting tired of missing small fun days due to a lack of volume, I'm looking for advice on getting a board that allows the same body shape (ie not leaning back on drops etc) but has enough float to deal with small days. Perfectly able to surf short boards in 2' plus surf but not able to rip like a grom enough for small days to be much fun on my regular board. Thinking more volume than a fatboy, like a fish or an egg. Any advice, pros cons or other suggestions greatly appreciated.
