Just thought I would update this thread.
Since my initial post I have been checking EBay daily for pads with a small top hat and angled in but generally they have been expensive. However last week spotted a pair of very nice looking Redback pads but were advertised as damaged as one had a very small hole. Perhaps the word damaged in the title put most people off as I won them on Friday afternoon for just £13.50 (+ £6.50 postage) and they arrived today. Anyhow with roadworks going on outside my house (I don't need much of an excuse), I nipped over to Stumps in Wakefield for a bowling machine session. I'll wait until I've scored some runs wearing them before heralding their purchase a complete success but it definitely felt much better batting with more compact pads.
