Thanks, dizzy,
I have a chance to try out a new driller in the near future (at the end of the month). This is a very rare occasion as, in France, drillers are few and far between!!
I might just get this ball anyway to try out the new driller. I've always thought that my span was a little short with my actual driller, but he refuses to drill me a ball with a longer span. He says it will give me tendonitis in my hand!

I've upped my average, so up yours!
