It just goes to show people new to bowls, that all the videos about how to hold the bowls mean nothing. John holds his bowl all wrong according to the videos, but he still bowls . And if you watch the videos about delivering the bowls, they all say is should be smooth, not to drop or bounce the bowl, like John does, but he still plays. And as for the line, Aero make 6 models, each with a different line. They also come with 4 grip styles. You can order the bowls you want through the Aero website, so you can order model, size, grip and logo of your choice, and they are competitively priced compared to other bowls you buy 'off the shelf'.
It would have been better to cut the ad and show all the range, not just 2 models. Also, we would like to see the line the bowls take, not just where they end up.
