Transition Mini-mal -> shortboard

Hey guys
Just got to cape town 3 months ago and have been surfing a lot since then. Currently surfing on a 7'8 mini-mal but as i've gotten better and the waves have gotten more powerful the need for "duck dives" and a smaller board has come up.
I was wondering how I should approach my next board. Thinking of buying something used, about 6'6 maybe with a little extra width to give me more stability. Do you guys have any tips? Thinking about maybe this board: http://capetown-westerncape.gumtree.co. ... Z295740789
I weigh 78kgs and I'm 1.74 high. Would love to get some input from the more experienced surfers.
Spots i've surfed in cape town: Muizenberg, Long Beach and Milerton
Also tried Durban(boardshorts were amazing) and Kitchen Windows in Jbay.
Cheers
