I think the diagrams are great, but in conjunction with pictures of actual bats, as I think for me it is easier to compare with what I have used and got on with, with pictures of actual bats. The profile definitely is better as a photo than a diagram, as I typically feel for me the profiles that are concaved, look more so in the diagrams than actuality. Further a slight side issue, pictures of a larger range of your bats on your website would be great, as again I find it hard to buy from a diagram.
But just my opinion, might be different for others.
