Is there any significance difference in playability between the Tricomp 90 and Response Graphite 90? Both racquets have similar composition: graphite, kevlar, and fiberglass. Head size and string pattern are the same. The only difference is beam width. Response is 19mm while Tricomp is 22mm. That implies the Tricomp is a little bit more powerful. Is there anything else? Has anyone play with both racquets?
