Before i knackered my back (and my younger years) i used to open the bowling or 1st change and bat around 6 or 7, used to open in overs games with field restrictions. ( oh they were the days )
Now it is 3 or 4 overs max probably 2nd or 3rd change before the back goes and still bat 6 or 7.
Thought about turning my arm at spin or just bowling 2 step military seamers as some of the dross i have seen this year gets wickets
