Matt,

It sounds as though Bowtech used this idea from the Diamond line that they took over last year. I have an original early 2004 (pre-bowtech) Diamond Gladiator (IBO 328) which has both a speed module and a smooth module that can be swapped out without a bowpress just by removing three small allen set screws. FYI, Diamond used to do alot of the CRC work for Bowtech so it was a logical marriage between the two companies.
