The last two seasons I've been playing at a much higher level than I ought to be playing in my opinion and I've had to adapt to the situation and change my bowling. So I've been bowling flippers coming in off a much longer run-up than I have ever done and it's worked for the most part. Only once have I been aware that anyone's sussed out what I've been doing and that was young bloke from one of the Southend teams who I heard say to his Dad 'He's bowling back-spinners' and he was taking me and everyone else to the cleaners.
I've kept it really simple, mostly I'm bowling cross-seamed with the occasional up-right seamed delivery. I vary the speeds and how much spin I put on the ball and rarely I try the one out of the front of the hand with a bit of off-spin, but I've found that rarely turns and if it does it's minimal. Recently at home I was thinking about the potential of the off-spinning variation and realised that it would probably work so much better with a lower arm angle. I bowl with a very upright arm and getting the wrist into an appropriate position to release a flipper with off-spin is tricky, but my initial experiments indoors seem to indicate that simply by lowering my arm may yield benefits. Another observation is that it still retains the back-spin aspect, so it does actually work it'll be an off-break with back-spin which is an unusual delivery.
