I have 2 7' quantum M rods. One is matched with an Abu Garcia SX40, the other with a Pflueger Trion 40, (both spinning reels) and I plan on spooling them with a braid. First question is what weight and brand of braid to use? Second question is I plan on using one as a Senko rig most of the time, probably the Abu Garcia, so I want to tie the Invizx 15lb leader on to it. How long should the leader be? And what knot do you all suggest? I am new to the leader game, and have never used braid before at all. Thank you for any help!
