Made from Maple instead of the normal Hickory of the 5A, however has stood up to my error prone hits on drum rims and lug ends well enough and are still usable after months of moderate but regular use. However signs of wear and chips at the tapers indicate nearly time for replacement.
Main benefit and difference over the standard 5A is that they are very light and therefore fast. Dimensionally they are exactly the same as a standard 5A.
Would definitely recommend, and certainly for a more skilful and accurate drummer than me, there is no reason that they shouldn't last well enough. Although I suspect a mega-heavy hitter would find them too light and flimsy.
