ive got 2 sw 20000, and yes they are ok for cubing and the old struggle with a beakie as your not exerting huge amounts of pressure normally set drag to say 5 8 or 12kg.
We are talking about a reel which would last a trip heavy jigging or throwing poppers in shallow water, i have done it and seen what a Gt or heaven forbid a dogtooth does to these reels after a short period of time under heavy drag.
I personally am not a big fan of paying overs for a reel that offers not much more than a $259 Fin nor, if i had my time again i know what i would be doing and thats not buying one of these reels hence why i tried to give some advice its amazing what advertising does to us,
ask any retailor that sells these reels to test the reels as what the manufactor speks suggest and they will not, as they no it s not achievable.
