I was wondering if anyone has ever tried to learn how to use their non-dominant hand after reaching a 4.5 or atleast solid level. (eg. a right hander learning to play left handed.) I'm sure there's no benefit to this, except maybe if you could learn a wicked slice serve off of your non-dominant hand. I usually do it for s**** and giggles. At most I'd rate myself as maybe a 2.0 with my left hand. Curious to see if anyone has done this and if they had any particular methods for achieving this rather than just practicing. BTW. I envy all you ambidextrous people out there.
