I actually keep a few cheapo reels just so I can reel line off to save it, especially when I cleaning my reels or whatever. I'll just reel it off, then put it back on. I would take that line off and save it, then add what looks to be about 15 yards of 12lb-ish mono, then add the braid back on . It will fill the spool closer to capacity, which should add some distance. More line weighs more, so it keeps the spool spinning faster on those long casts. You're also killing your IPT by having a half full spool of line. When a reel says it takes in 29" or whatever, that's based on having a full spool. Take off 20-30 yards of line and that number goes down to 21-23"
