As I remember, coolingworks had plastic external springs. No idea if this is still available or if it ever existed for the OD of whatever tubing you're about to use. Hardware stores are good places to find lots of different springs.
If you have a really tight bend, think about using thin wall copper tubing. Many radiator shops can not only bend this stuff to your spec but can also "bead" the ends, so you can push flexible tubing over the ends.
And then there's just using thick-wall soft silicone tubing, which is slightly worse than thin-wall at damping vibrations, better at stopping through-tubing-evaporation, and basically won't kink unless you try to kink it. The downsides are that it's thick (duh), and comes in dull orange, and, is expensive. BTW, if you're using low restriction blocks, there's pretty much no need to clamp it, particularly if you use 3/8" ID tubing on 1/2" fittings.
Hrmm... thinking points.

Color of the tubing is the least of my concerns, though transparency seems like a Good Thing (tm).

While not needing clamps if I use a low-restriction block makes intuitive sense, the pessimist in me wants to anyhow - there does not appear to be all that much of a downside and the added insurance seems worth it.

Do you have any opinion on the Norprene tubing? It seems to be favored highly by Gabe of SwifTech.
