I would love to catch one of those bluefin! I run a mix of tld 20's, avet hx's and a shimano tiagra 16. All of the tld's are straight 50#, about 300 yds. the Avets have 300yrds of 80 braid topshotted with 100 yrds of 40# mono. The one heavier setup I run is a tiagra 16 loaded with 550 yrds of 65# braid and 100 yrds of 50# mono on a calstar 20-40# rod. I almost always run the heavy rod as the long rod down the middle with a purple cedar plug. Its a bit of a toss up..........do you fish heavy gear all the time for that bluefin tuna and just bomb in the albies or do you have a litle fun with the small tuna and take your chances with the big guys..? On the right gear these are spuper fun fish, also I find that the 80-120 flouro leader is way stiffer and tougher than the equivelent mono. I have been using ANDE flouro crimped on both ends as it sucks to tie knots in the heavier stuff.
On the subjet of poppers charbait has some nice yellowfin coffin nail poppers on the bottom of the page

You are going to need a good quality spinning reel and some 50# braid for this. A baitcaster just doesnt give you the speed of retrieve that you need for these things to work well. No matter what happens DON'T STOP REELING.....when you have a fish chasing just KEEP GOING.....maybe even faster. I have found if you slow down they will loose interest. We should all get together this winter and share our ideas on this fishery as it is always good to get other anglers opinions on what works.
