Im lost as to why every one here goes for Starboards other the the fact that they are easy to come by...
Dont get me wrong Starboards are definatly good boards and i have a 10.5 drive and i love it for a long board style SUP but in my opinion if you want something purely for surf you should be looking at something that is a short board style SUP..
I have the Drive for longboard style SUPing and a 9.4 Jimmy lewis Mano for when its a bit bigger and heavyer

Again its only my thoughts but if i was you id go the JL 9.9 Mano or similar (a short board style SUP).. You will lose a tiny bit of stabilty but you will get used to it very quickly and once your on a wave its a lot more like surfing a short board then a long board..Both are fun but keeping in mind you already have a Drive i would be going something completely different..

Hope that helps Belly
