Since it's been said that 80-90% of the playability of the string job comes from the mains, could you just use whatever you liked for mains, and use something cheap like Gosen Synthetic for your crosses? I guess what I'm trying to say is many do it w/ Natural Gut, bring down the cost to about $11/string job. But I don't hear many doing it w/ multis such as NXT, NRG2, LS Supreme, Prostock, etc. which would bring it's cost down also. Also w/ polys like the Lux line. Your opinions are greatly appreciated.
