it depends on which one you like the best in plastics we are still using plastic that I've had for over three years I like Calhoun and also Luer craft we are currently using their 502 which is good stuff there are so many different grades of plastic out there I couldn't tell you about all of them just those two so far I like Luer craft the best because it does not have any bubbles when you are steering it doesn't have smoke in its very easy to work with but it is expensive I think all plastics nowadays are expensive it just depends on you on which grade of plastic that you like the best you may only want to buy a pint to try out to see which one you like the best I'm sure the other guys well charm in on this eventually I've also used candy Creek good stuff little smoky but good quality plastic.
