Moving down-Rounded Pin or Squash

Wanting to move down in size to a shortboard from my 7'9" Bic that i started on.
Was thinking of going down to a 7' Epoxy but the board im looking at is a rounded pintail.
The aim is to learn to surf bigger waves and get the general shortboard skills dialled.
Ive been reading conflicted views on the rounded pin Vs the squash and am wondering will i be left flapping around like an idiot on smaller surf having wasted my money on a rounded pin,due to the fact that people are saying they are suited to larger surf.
My local surf would be medium sized,sometimes big,not always the best conditions but good often and im 6' and 10.5-11 stone.
Any info appreciated
This is the board i was looking at but they dont come in a squash but im liking the specs on it as is:
7' Epoxy
20 1/2" wide
2 5/8" thick
Single concave
looks to have a nice rocker on it aswell.
This board has been the staple of the Tiki range for over 10 years. The long rail line of the round pin tail make it a solid step up board for those looking to ride bigger waves. For the intermediate or heavier surfer, it offers performance from a board with plenty of float.
