My girlfriend and I joined one of the summer leagues this year.  There is an older guy on another team that feels the need to give my girl tips.  One of the things he told her last night is very different to what I have heard in the past.  She threw one of the nicest balls I have ever seen her throw and when she returned she said she felt a burn on the her finger tips when she released.  I have always heard that was common, especially when you are just learning to throw a hook shot.  He told her that it isn't good and she shouldn't feel that and that she is probably squeezing the ball when she releases.  Which is correct?

Thanks.  I am not sure what it was due to.. She hasn't complained about the fit or bevel so I assume she was referring to the lift.  I'll have to ask her tonight. Thanks.

She should feel a "heavy-ness" on the fingers at release not a physical burning sensation.

A lot of the time if you physically burn the tips of your fingers to a brownish tint then your span is too long.

Otherwise like Mumzie stated it the fingers may just need additional bevel or they might need to have some reverse pitch put in the fingers.
