I think Dan S. is right about Crystal Ivory on a spinning reel. Set-up my 9' spin rod for side drifting 12 lb. mainline a small lead dropper & 4' 10 lb. leader. As soon as I got any slack in the line the C.I. started springing off in big loops, glad I tested it before hitting the river. I'd like to stay with 12 lb. on the reel, any suggestions? How does the Izorline compare to ultragreen in 12 lb. on a spinning reel....anyone
