I bought a bulk spool (10,000 ft) of 7 strand Blood Run on sale 4 years ago and have had no problems. Loaded several reels for others along with my 3 for about $20 per 1000 ft. Still got enough for a few more. We run 40 or 50 lb mono at the end to eliminate the curly Q's. Before that, I tried the 19 strand Torpedo on one reel and besides being more limp didn't notice any major difference.
Merry Christmas!
