9/27/14 Update: I tested my strategy of fusing the 15 pound test Trilene Big Game to 30 yards of 50 pound test Power Pro yesterday. It casted pretty well and I landed a nice 9 pounder on it. As I need to replace the Power Pro on my other reels, I'm going to use this strategy. Instead of 4 new spools annually and occasional replacement spools of Power Pro throughout the year, using the Big Game in conjunction with the Power Pro should save me $150 - $200 a year.
I just finished spooling up a test reel with 225 yards of 15 pound test Trilene Big Game monofilament fused with a uni knot to 30 yards of Power Pro braided line. I think I may have put on too much monofilament and not left enough room for the Power Pro. If the first try doesn't work, I'll just make adjustments and try again.
