Welcome back Stacie. Paudie is around somewhere.
The best bet is try out a few boards if you can. Depending on how the forecast looks the LBI weekend is on in brandon Bay next weekend. There will be loads of stuff to try out down there.
It's hard to give advice without knowing them but if you have been riding something about 7'2 or so you could go down to 6'6" or so in one transition if there is some volume and width kept in the board.
You might consider a 6'6" Quad (eg. Powersource retro fish 4 fin) or a bear wombat in that size.
Or talk to Glide and he will make you what you need.
PS just had a look on Powersource website, this looks like it would suit
