Just thought I'd share this one, my games moved up another minor step after spending just a few weeks solo practice on it.
Its very simple, colours on the spots last red over the middle bag with a simple stun angle on for the blue to give position on the yellow. (Or play black to yellow if you prefer).
The object is to clear the table and go until you miss, my best is 110 which was clearing 3 times in a row then to the green on the 4th attempt.
I played a bad positional shot to the brown and wobbled it.
It has really helped me in league games when I'm in this situation I'm now very strong at clearing up from the last red or couple of reds. Before I wasn't so good only managing it now and again.
Give it a go if your looking for a new routine and let me know how you get on.
