Hi Femi
In general, maintaining the shape of the right (back hand) at least through impact, will make for solid reliable contact. If you choose to use it to (as you say) hit the ball generously, that may mean you’re not holding the shape through impact. Once the club head is changing before impact, it may cause miss hits in direction or solidness. BUT, if you are having success, use it. I don’t teach to hit with the right hand.
