I play a traditional penhold style (meaning I don’t use RPB/reverse penhold backhand very often, still trying to improve my consistency with that stroke), using one side of paddle for FH and BH strokes. My traditional penhold backhand is decent, serves are a strong point of mine, and I twiddle decently, sometimes after serve and occasionally during a rally.
I am trying to transition from LPs to frictionless anti on one side, currently using DMS Scandal 0.9 on my ALL blade. (Amir Ahmed’s inspiration has me trying out SPs again, though I traditionally use inverted.) I am a super-newbie with flanti
Against tougher opponents, I tend to use flanti on FH for serve receive nearly all of the time, blocking emulating Amir’s style. I’m still trying to work out when or whether to twiddle back to inverted for attack, or just let the backspin hopefully accumulate for the opponent if I can keep blocked returns on the table, as most opponents aren’t familiar with anti yet. 
Any tactics or strategies to share? i.e Maybe wait for a push and twiddle to attack then, etc.?
