Hi Magtellus,
I would recommend either a 90cm barrel, or a 1m to start with. I hunt a lot in the kelp for bigger fish, and a 1m is adequate, provided you put a good strong set up rubbers on. If you start diving more open water then you can consider a 1.1m, and 1.2 or even 1.3 if you dive Struis or others. A 09 is nice to handle, but if the water is clean and you find some big fish it might not be enough.
But in Cape Town I still use 1m and 1.1 for hunting tail off a boat, so that 1m can be a nice utility gun. Living in Stellies, I guess you will be diving Hangklip and beyond?
Guys, any other opinions?
Cheers,
Tony
