the Air will be fine .
My outfits are pretty much the same you are using , I however have another 9 foot outfit , with 30 lbs Fireline and 50/60 lbs FLouro , just if theres those big Struis Tail around .
However , in CPT they get big , but not the sizes you can expect here , so your 100% .
RObben Island , the Water MUST be warm to produce tail . There also might be some Geelbek around , got word for the guys in Buffels they got some Bek in the week , although its on the other side of the peninsula they might show face thats side too .
Get some spoons , if they are there most spoons will work , Wally wicks , Steve Champions , keel spinners ,ashley reads , Snake Spinners AKA dakplaat . Snake spinners are the most popular amongst Tail hunters and commercial alike , you will still often see Penn 49 with 50 lbs mono old Glassfiber rod and a big Snake spinner on most Commi boats
or you could just get a yo yo , with 100 m 75 kg line , some 6 to 8 ounce boat sinkers [ the ones with the swivel at the bottom ] and some 10/snoek hooks and some Pumkin or Red Dollies/skirts .
wind is howling here , so we can only talk Tail fishing for now...
Enjoy !!!!
