Model Expo sells several different kinds of line. It sounds like Dave got some of the inferior stuff. The stuff I've bought is labeled "cotton poly mix," and comes on black plastic things shaped sort of like flat spools. I've been pretty happy with what I've bought - but I honestly don't remember whether it was called "hemp" or something else. It does have a little bit of a sheen to it, but that doesn't seem to be noticeable once it's been handled and set up.
I don't recall that it retains kinks from the spool. If yours is doing that, you can probably get the kinks out by dampening the line with water.
It sounds to me, though, like Dave and I bought different products.
I don't think Bluejacket sells any Caldercraft products. The Bluejacket catalog does include cotton (not recommended), nylon (ok with reservations), and linen line. Lots of old-timers swear by linen, and it's certainly good, durable stuff. It used to be possible to get linen fishline that had a real ropelike lay to it. No more. The Bluejacket linen, to my eye at least, doesn't look much like rope. It would be great for spinning up with a "rope-making machine," though.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
