Mono ....... no need to justify the need to use quality gear on those babies ....... That is why charter boats run reels like internationals , tiagras , stellas & saltigas ........ No W_nk factor there.
Like any tackle though ...... you can catch great fish on very cheap gear - but try to continue it on a regular basis ........ CRUNCH , CRACK & BANG

PS ..... It IMO boils down to the application & technique used ( I still use a 10 YO ugly stick & Baitrunner 4500 for snapper fishing with floaters - - - cannot fault it would I want to use it for plastics fishing for reds ...... No way )
