I'm looking for a wax that I can buy in bulk (900gr.) for typical Sierra conditions. By this I mean those days well past a storm when the temp might start out in the low 20's and end up in the mid 30's and somewhat transformed.The only thing I've really seen is a Swix CH7 900gr. block for $75.00. As a longtime xc ski racer, I've always thought Swix was an ok wax but not the greatest value. By the way, anyone got experience with Swix glacier wax, (blue) supposed to be hard, durable and dirt resistant. I just scored 900gr. for $40.00 from Reliable Racing but that's for late spring conditions.
