I thought id update, that I use ALUMILITE.COM exclusively now.
Their quality is head and shoulders above smoothon products. Every product I have used from them, has been top notch, and any problems I have had (That ended up being my fault) they took care of anyway.
I have molds that are 2 years old, that have been stored in freezing temperatures, that still make great pulls, and their resisn are MUCH less brittle.
