i have the 9' medium model, matched to a biomaster-sw 8000HG.I use it as a flog around rod spinning up bonnies etc. its good value for money and very robust. I've caught a 14kg longtail on it and felt very undergunned.
2 of my mates have the 9' heavy model, and although they pack a punch they are very uncomfortable to use and difficult to cast and fight fish with. My mate tried popping a 100gr Cubera with it... with much difficulty. might be better suited to stickbait work.
i have noticed across the board though is the poor epoxy coat on the guides. My friends and i maintain our gear well, and we all have rust developing where the frames meet the epoxy.
overall, they are great value for money and i think they are easily some of the best in their price range. As already mentioned, very robust and solid performers. but i dont think they are ideal for what you want to do
