I have a 167 GL Fury competing against two Rivers (seasoned 168 GL, fresh 164 Opto) in my bag to take over the understable spot.
So far I get more controllable lines and a nice slow turnover when thrown flat. I think the increase in speed makes it stable enough for me where it doesn't just turn immediately out of the box like Rivers can. I'd liken it to a newer Opto River but a bit longer.
I'm curious to use it a bit more and see what it really has going for it.
