Continental, Semi-western grip forehand

[oray777]

I'm comparing these 2 grips for the forehand side. I usually use a semi-western grip. When i hit flat shots i just turn my wrist up a bit to hit more flat shots and when i hit topspin i just turn it back to semi-western. Is this good practice or should i change my grip to continental when hitting flat and then when hitting topspin switch back to Semi instead of turning my wrist.

Do you mean eastern or continental?

Well i'm left-handed so say i'm holding in the forehand direction i turn the racquet forward a little so i suppose it's the semi-western.
