Hi BDer, I have a new Avet LX raptor and it is spooled with 300 yards of 80lb JB non hollow braid. After fishing it for several times I found out I want to fill it more with 80lb braid to the existing spool. Now here comes the question. The existing JB on LX is only a month old, so I would not want to get rid of it and respool a new one... I am thinking of getting a short piece 80 lb hollow core and splice one end to the existing spool. I have another new spool of PowerPro super 8 80lb, so this goes to the other end of hollow core, and probably runs close to the end of the LX (extra 150 to 200 yards from the original 300 yards JB on the LX). Is the splicing of two different brand (same test strength) braid feasible? Do I need to serve the splice with nail knot? How long the short hollow core should be? Thanks in advance!
