To be honest the ride with the v3's were much more comfortable yet still handled superbly, with all the handling mods I have it certainly brings the creaks and rattles to the surface, but I suppose in fairness clubsports aren't designed with comfort/silence in mind especially on the rough uk roads, they do there job very well though.
I would definitely look at getting the Ast's over clubsports, don't you have v3's already I really can't fault them myself, maybe you should look at stripping out the interior and having a full cage, I would be up for a group buy from custom cages
