Ok, so I was trying to figure out what to do about my tems sprocket problems, i loked at two leftovers from SPI from last year. Stamped on them was the word <b><i>Martin</B></I>. So after a little research on the internet i found
http://www.martinsprocket.com/. These are the people who make sprockets for SPI! there for order it from them, skip the SPI problems and still get by within the rules. Sounds good to me. Oh and lok on your old sprockets to see if i was right about the Martin stamp on it!
