The less skilled the better as far as I'm concerned.
I consider myself to be fairly average, and as this is my first OLR series, I've never stacked myself up against other players. (Except for marvelling at some of the lap times set around the 'ring...

) Anyway, all my mates are crap, so I get no measuring stick there, so the less quality people that enter, the higher chance I have of winning something.
As for El Capitan, the sport tyres thing is a bit of a downer, but I think
nitro_2005 picked it because El Capitan is the most similar to the famous Bathhurst, what with the long straight into a sharp corner, a step climb up the mountain and back down again... A good choice IMO, but I wonder what will happen about the tyres thing?
