I've always liked Gates products and gotten good support in the past. For
this reason I specified their stuff in a major plantwide retrofit (many
thousands of dollars) for one of my clients last year. The Georgia Gates
rep (Paul Clark) treated my client so badly that I have since made it a
point to avoid their products when possible.

As for cog belting in general, I have looked at several. The new steel or
kevlar reinforced belting is incredibly stiff. However, I think its thermal
coefficient is still quite high. Guess I need to verify before I make
another dumb assumption though.
