I now have gotten all the golds of the original + gamma + delta with my trusty AG-5Y5.
Besides, every first position in my single race and time trial record tables is AG-Systems except Vineta K / Vector / TT where I can't beat my current Piranha record with the AG-Sys.
I guess a 5 in speed is too hard to beat with a 2 in an easy circuit at a slow class.

I suppose that as soon as the WOZone tables are up, most TT Vector records will be done with the Zone ship or similar. :-?
