In theory it is nice, but in practice it is not the case. When the speed of the ball changes drastically, the release points differ so much, it's like an announcement of the pace that you are going to ball. Visit Shane Warne's flipper tutorial, and he asks to keep the same arm speed (or slow down a bit if possible) for a flipper, because the natural tendency to bowl it quicker (and hence noticeable). In addition to the release point the trajectory also change drastically.Who said that Barnes bowled at the same pace all the time?
When opening the bowling he would sacrifice turn for pace; and as the ball and pitch started to wear he would ‘give the ball some air’ as it were.
That is, drop his speed from 70mph (Bedser) to 60mph (Swann).
That is why spinners are asked to make subtle changes of pace and flight. Massive changes are noticeable. A drop from 70mph (Like Afridi) to 50mph (like Warne) as massively noticeable to a player with international quality. Barnes would have not been this successful changing between 50 and 70.
