Maximum Throw, Lens Questions

[Nos]

Hi guys, i just found a cheap lens shop who offers several high quality optical lenses.

my questions is whats better for maximum throw and why....... at the same diameter of course :thumbsup:

a high quality bi-aspheric plastic lens, or a plano convex lens made of optical grade crown glass?

I don't know of any CPFer experiments with biconvex lenses, so I'll give the standard CPF reply: buy both.
