If it doesn't feel comfortable and doesn't work, don't do it. Nothing seems to mess with peoples head more than putting. I see lots of different grips being used nowadays, but I've stuck with my "traditional" grip as it works for me.
Lots of people will give advice. For me it's maintaining a smooth stroke with a short backswing and longer forward stroke with good follow through as most things are stable under acceleration (a trick I learnt teaching motorbike riding).
