For some reason there's tons of French and Canadian drivers that are usually dependably fast. No idea why but yeah. I haven't heard of the names you mentioned. But mentioning French got me thinking of another very good driver named GTP_lapierre4.
Hmm, go ahead and add me on PSN sometime soon. I'd like to get a few runs in with you in some recommended garage cars to really gauge your level. Also, are you going to show up to the GT4 cup races? You missed the Saturday pre-season race @ Suzuka. R1600Turbo's running in that one. I'm participating in it with the C6. There's a lot of extremely quick drivers in that field. Aderrrm (creator of the series) is one you'll have plenty of trouble keeping up with as well. Moleman, w-g-e, superdan, NEPALII, outlaw4rc are the highlights. They can easily bruise an ego or two.
