It looks nice. I like it. I don't see the point of having two wraps, I've always said it. Nobody can hit a fish at a two wraps distance with a rail gun. At least not with decent penetration power.
I too believe this 100%, but i'm looking at it from a business standpoint- what the majority of divers will think, and what will SELL. A lot of newer divers will use a double-wrap no matter if its pointless. For myself personally, I use a 1.5 wrap on my 120cm because I run a breakaway for Jobbies, Wahoo, and Mahi. I don't think that line release style wouldn't hold my breakaway setup very securely. just my 2cents.
That line release reminds me of the Cressi Geronimo Pro. I know a guy that uses that gun and thats his #1 gripe with the gun (the line release). He said if the line isn't TIGHT or when the mono gets stretched out, it pops out from the part that you route under on the handle and the line comes off the line release.
