First time I tried a Hammer thing (possibly the first one) I hated that piece of shit!
It deserved its name: balance is outrageously headed, making this racket unuseable at the net for me.
Also hated the size (100Sqi and plus is too large to my taste).
By that time I was using (and have been using it until 2003 or 2004) THE :-) Wilson Pro Staff Classic (black, yellow, red, ala Edberg obviously) 95Sqi 80%Graphite 20%Kevlar... A heavy and non-forgiving superb tool.
Wich I replaced with Babolat Drive (sublime balance, stiffness; in a lighter package).
I play with it since.
If I was to buy something new I would defintely try many models, especially from Technifibre, wich released some incredibly good rackets few years ago.
Try as many as you can: borrow from friends/parteners/clubs...
I tried those technifibres during club/brand evening test session.
