Over the past few month I have a few conversation about purchasing a SM bat (for my lad), only really because they are so cheap compared to a standard short handled bat. I contacted a retailer in oz who sell an xxx8 SM for a fraction of the price of a standard SH xxx10. Was told that the blade widths are 105mm and the quality of the willow was not as good as the Standard SM. They also only went up to 2.6. In the end it was cheaper for me to buy a 2.10 xp70 and chop 15mm off the bottom. So he has now got a SMs full width 2.9.
Why do the manufacturers think a SM would want a child's bat. Surly they should produce full width super short blades as a SMs bat.
