Hi Morgan ,
My Rompin sailfish popping outfit is a Carpenter BC75MHS mated with Daiwa Z4500 which I prefer over Stella 8000FA due to weight consideration , I use PE5 line for the task and for the past 4 years have been very happy with the combination . I use the same combination for targeting school YFTs up to 25 kg and have caught colateral targets such as tenggiri , mahi-mahi , rainbow runner , etc. in the process . Your choise of which Twinpower should be on weight but there is no reason to buy a Twinpower 12000 and then buy a #8000 spool to go with it for lighter line , in my opinion .
Jon .
