I actually love this line. However I use 17lb test, I have never had line snap nor a knot fail. Yes it does get memory if your reel sits for about 2 weeks with out use, and there will also be memory on about 25ft of line after 8 hrs of use. Simply spool the reel with a decent amount of line. You can also cast the memory out if you are using a heavy 7/8oz weighted lure.
But I have found this lines best use is while using a Texas rigged lure, or wacky rigged. Not a good top water line at all.
