Hi, I have a few questions regarding the specifications of some Dunlop racquets. On the European Tennis-Warehouse site the swingweight info of the "Dunlop Biomimetic 100" and "Dunlop Biomimetic 200 Tour" racquets is left blank/open in the specification section. Could you please provide me the swingweights of these two racquets? Also the stiffness rating of the "Dunlop Biomimetic 200 Lite" and "Dunlop Biomimetic 200" is listed as 57 and 62 respectively on the European Tennis Warehouse site, while on the US Tennis-Warehouse site the stiffness for these same racquets is listed as 65 and 57 respectively. Why is there such a large discrepency between these numbers? Are the European versions of these racquets different from the US versions? If not, what are the correct stiffness ratings for these racquets?
