Does the DSC really need to look at a seperate class for 748s there is already the Sound of Thunder class which usually has a few spare slots on the grid, yes it will mean racing against more powerful bikes, but you only need to get a handful of 748s out there and you have something similar to the handful of 583s in DD against 620/675s, I know I've been there.
DD is about cheap racing other classes for Ducati bikes are Minitwins and SoT, nice to see TP having a go this coming weekend and Garry Smith, Felix and others would be quite happy to have some other DSC guys to race against, two years ago there were at least 3 DSC members in the North Glos SoT championship.
Here's hoping its wet at Brands
