in the heavier weights?

I've fished some of the standard's in the 300 and 400 grain but got my hands on the shorter version in a 225 (so my box says, catalog doesn't show that one) and absolutely fell in love with it.

Has anyone fished the heavier versions, say 265 on up?

Airflo QuickMax 28

I don’t see anything on there web-site about a shorter version ether.

The ones that are listed are 200 grains and 230 grains lines with a head length of 30 feet.

By looking at the specs (of the 30 footer) it’s a chuck-n-duck line.

I made similar lines for single handers but with shorter tips.

Mono core lines sink better than regular core sinking lines that a plus.

You might want to talk to Sparky about this.

Added some more.
Looking at the specs some more it looks like a Jim Teeny line.
