I've seen this question come up regularly. It is usually regarded that stainless steel is superior because of its higher thermal conductivity, but I can't find a quoted measure of how conductive vinyl hose would be. I think this is because "vinyl" hose is often used as a generic name for clear tubing...
I say give it a lash, use plenty of tubing and see what happens. Worst case is you have plenty of siphon tubing spare if it doesn't work out...
