I thought I would offer an update on how the 'Small Adult' experiment went.
I will qualify by saying that I've only played a couple of games with it, so if I had time to give it longer there is a slim chance it could work for me.
However, I don't think it will make a difference.
My Blaze is very light, at around 2/4 I think, and ultimately it is too light. It seriously lacks the power to make big shots, especially with my limited muscles.
I've been out twice now basically due to the bat (.... kind of) - both times I've been caught short by the lack of 'go' after timing it well. I found the increased vibrations through the handle really frustrating too- it made it feel flimsy when batting against a not-very-sharp bowler.
Whilst my RPC is very, very dead, it is for me at the moment a better bat. In the future I'd probably look to go for a SH at around 2 10 to see what having a little extra weight could do for my batting. I miss the power!
I think there is probably a place for small adults bats, but unfortunately it isn't my kitbag.
