That was my issue, so I decided to go to try the ball marker with it coloured red and all other lengths white (because I play them off the front foot anyway). It's not ideal - I don't really like having a big circle on the screen - but it has significantly reduced my premeditation.I haven't been playing with the pitch marker since DB14 but I must admit that it leads to premeditated shots (and misses).
I will however never manipulate the crease to create scoring areas.
The dismissal that bowled me yesterday was delightful, I'd have shared it but I have technical issues.
