Just checked their stock shots again, and the concaving, spine and edges all look exactly the same to me. I guess this proves how little stock photos reveal about a bat. But even GN's descriptions about the shape is exactly the same for both bats!
I had both the e41 and A61. Very different profiles. However, I might be wrong as the A61 that I got was a player issue pre-release bat, so not sure if GN Aus have made any changes to the profile in the last 6-10 months.
As per GN Aus, the e41 has a slightly lower middle than the A61. But the A61 that I got had a pretty long middle.
The A61 I had was very similar to M&H Distinction from 2010/11.
The e41 uses better grade of willow than the A61 - at least for the shop bats.
Agreed, stock pictures are very misleading - looking forward to seeing these bats @ Lord's
