just copied and pasted this question into this section. i think i had it in the wrong section before. just wondering the following, maybe some help from any of the pro stringers/tecnitians around: 1. What tension/string does berdych use on his: a/ head frames b/ his old dunlop frames of 2009 and any particular pattern he prefers (one or two piece) ive heard 54 or 55lbs alu power 1.25, but mixed opinions on one or two piece 2. what weight/balance/specs his a/ head frames have b/ dunlop frames had i've heard a rough estimate that his dunlop frames were around 355g and slightly head light thanks!!
