NE Tuna guys - looking for gear input -

[oldbluesplayer]

I'm gearing up for Charlie for next season, have picked up some Senator 113h and 114h's, and some 6' 50lb rated trolling rods, looking to troll a 4 - 5 rod spread -

Would like some input on line - I believe I prefer to stay straight mono, but am open - thinking to just spool up with some 50#, but could pack more on the 113's if I go with 40#, but worried that's a trifle light ?

What's everyone using, weight, color, brand ??? If colored, how important is some flourocarbon leader ??

Also, lures - have a couple GM, and a couple birds/daisy chains - are spreader bars a must have ? I see mixed feeling on them elsewhere, they're expensive, and I think hard to troll a mix of spreaders and bird/daisy chain rigs ??, especially off a small boat -

Outriggers vs rod riggers? - how well do the rod riggers work ? Decent or a poor excuse alternative ?

What works, what's the recommendations ??

thanks

Bill
