softer, easier to work with, especially when cold.

Evan,

What about using silicone rubber tubing from McMaster-Carr . . .
unlike "latex", *excellent weather and ozone resistance, better
temperature range too. In my experiece, which doesn't include smiley
bag applications, latex doesn't last all that long when exposed to the
elements.

(sorry about the hijack...) The tubing I am using is #5234K61 1 x
1-1/4, black. Shore 35A (very soft, stretchy, doesn't take a set).
It's more durable than you think, and I think many people would
mistake it for silicone. Two seasons, doesn't look any different than
new. Nothing wrong with silicone in general, but I don't see anything
in the catalog that I'd use in preference to the latex.
