Using Korean penhold

I use shake hand grip with hurricane 3 neo on both sides 

My friends use Korean grip and I tested it and I thought it was ok can you put rubbers on both sides of the blade and how do I tell my coach I'm switching without him going mad?

Hi Dayton,

II think you need to think about what suits you personally first.  If you try it and think it is best then try changing for a few weeks and see if you still think it will work.

It is difficult to use the other side of the racket with the Korean or JPen grip soo think about whether this will suit you.

Regarding your coach, it is important to discuss it with him and show him what you are thinking first.
