i dont know where you live. but at almost any pro shop, they have package deals with a handle and a non stretch line. coated and un coated are available. i prefer coated, but thats all preference.
but they can be found almost anywhere for pretty cheap
i dont know of anyone that has ever done this
but the link im about to post is often put on winches.
its what i have on my winch actually.
but its very cheap. and non stretch. its really small when you get it. but supper strong. way stronger then it looks. i dont know what length you ride at. but you could buy 100 feet of it for only 14$. you can order it from 1 foot up to 600 on a spool.
might be worth thinking about doing that if you want very in expensive. the only downfall i can see to that, is no pre set lengths. but that couldnt take to long to do yourself http://www.seattlemarine.net/productcart/pc/viewPrd.asp?idproduct=9374#details
