I'm going to have to say +1 for Hexy fiber and RIPc. I've been popping Hexy fiber around the 5-9 hour mark, but I've been swinging pretty aggressively lately. Definitely more power and (IMO) better feel. I'm actually going to move to RIP for less power, but i've played the 16 and reaaaaallllyy want to try the 17. I'm looking for a reel to buy or someone to give me a set lol.
If you don't mind premium prices, I met a solid 4.5 in another city that loves Gosen Powermaster. I didn't get his impression of its durability though.
