RE:SA clear intermediate striper line.
Not what you needed when there are tunoids around... zzzZZZZZzzzzzzzzzz OW!
Bean's always been good to customers.
I've had great luck with the 444 clear intermediate and it takes a nail knot perfectly well. I beat the snot out of it and it's been great.
The Rio non-clear intermediate striper line is kinda-semi-clear-ish but very stealthy and a good line. I got a prototype before they released it, fished it for stripers on the east coast and coho salmon on the west. My friend Brian fishes it for salter salmon out there, in fact this time of year. Jeff Roop told me he likes it too, claiming "it's ribbed for my fishing pleasure".
The line has a slight (very slight) ribbed texture that gives it a lot of substance in the hands when stripping line, etc.
The Rio clear is another good line. I also fish the new Deep Sea, which although it doesn't have the no-brianer easy cast feel of a 444 QD, I am confident that the joint between running line and head will not disintegrate in a few months. It's caught a ton of big fish this season and I think if they figure out the taper and grain distribution a little better it will be best choice for the sinking head type lines.
