Towrope sources

Hi,

As many of you know, I sell soaring supplies. I would like to add towrope
and accessories to my inventory. I see that Tim Mara has a nice selection
of towrope on his Wings & Wheels site. I would also like to help support my
customers by having a lot of towrope and accessories in stock. Also, I need
a bunch of towrope for the Region 7 Contest in Minnesota in May.

I've done some searching for manufacturers and haven't had much luck finding
a good source.

Given the great number of experienced glider pilots that read this newsgroup
I thought that you may have some advice for me.

Where do you buy towrope in the USA? How much do you pay for 1000 feet?
What size rope do you use?

I'm looking for 1/4", 5/16" and 3/8" hollow braid polypropylene rope.

Upon finding a good source I'll buy a lot for inventory so that I can get a
good price and customers can get it when they need it.

Thanks,

Paul Remde
