they are junk. the plastic stems slide out of place and split, catching your line. I think most raven stuff is junk though. pikers all the way. still got the same one on my line since late September.
I use Berkley 10 lb as well. probably a bit stiffer than the lines that are made specifically for float fishing, but 11$ for 1500 yards works for me. its also strong and can take a beating. haven't lost a float yet.
One time I watched a guy nail 5 steelhead on 6 drifts. Each one he leaned over and popped hook with his hemostats. Didnt touch it, no iPhone shots of flopping fish on rocks. A true fisherman.
