yea with no problum the Avet MXL I have 4 of them and I love them ive caught every thing on them from snapper to sharks sailfish ,grouper, 18# mutton snapper, 63# cobia , big Ajs ,king fish,permit off the bridges in the keys tarpon snook it is a great reel for just under $200 parts are easy to find and best of all its made in the good ole USA =D> but the reel is great just buy different rods for what your fishing trolling yea I would say a 6' to 6'.5'' for live bait fishing 6'.5'' and for a surf rod or pier rod I say 8' to 10' and just swap the reel out
you dont need anything crazy for mahi yea they are fun and a great for dinner but a 15# cobia will fight harder then a 40# mahi lol so you dont need a huge setup the avet is light easy to fix and cheap cant beat it . also the diawa saltest I have the black& gold 20 and that is also a great reel equal to the avet hands down. the old penn 4/0 are good old reels but super heavy and are over kill for a mahi I have a few 4/0 full of wire line for wahoo . if anybody has any ? just pm me i'll be happy to help . because you guys are helping me out with this hole freshwater fishing thing this is all new to me .
