Tricky but interesting question

[xwall]

I was training with a very good tennis player the other day, and when we were talking about racquets he told me something that I have never heard or thought of before: That you can increase the size of the holes were the strings are running (with something with a smooth surface, like a round nail etc) in order to give the racquet (strings) much more dwell time, power and livelier response.

He claimed that some racquets have very tight holes, and that it limits the strings way to move and slide properly at contact.

He actually claimed that many serious players, or their stringers, always does this when they get new racquets.

I was instinctly thinking of the newer Prince racquets, and why they have gigantic holes.

Was his information correct, and is this useful on some sticks?

*I was actually trying his racquet (a Head Microgel Prestige 93 cm2 18/20 with polyesters at HIGHER tension than I have on my VERY STRANGE Fischers) and to my great surprise, his stick gave me MUCH better power, spin and dwell time.*

Your humble gear freak :D

I have nothing useful to add other than to thank you for a very interesting read. I've never heard of this technique before your post. It makes me think, I have a Radical MP and it has some tight holes and is a bit low on power. Perhaps when I feel bold I'll have to give it a shot.
I'm sure some more seasoned racket techs will chime in sooner or later with something more useful.
