Most bow models have a life span of about 2 years, although they will continue to make that bow longer if it sells good they often stop marketing it after the second year and focus all the advertising dollars on the new stuff. The DXT is 3 years old now they came out in 07 so it has run its course. The drenalin and DXT seem to have a better following by the folks that have been loyal Mathesw shooters. The reezen and monster having a more aggressive draw cycle is a departure from the smooth draw mathews bows were known for.
