Let's say you are a decent driver and you'd have an access to get yourself a brand new S2000 car. To which series you would take part next season ??

To IRC where there are new and exciting rallies, try out different rule-set, you would get probably much more TV-coverage but the competition woud be lower than in PWRC. You would seriously need to think does it matter but since you have a determined plan to some day reach the vey top of rallying, professionally it clearly won't feed you as much.

Or, to PWRC where the compettion is much harder but you had the chance to circle and get experience from rallies used in WRC. Should you do well, especially in tarmac rallies, you would probably fan the team bosses of WRC early on your career which would naturally be very important.

If it was me ( hey, I'm another flying finn ) I'd choose PWRC in a second and had a head against head battle with the boys ( hopefully not girls since Natalie isn't so fast ) of PWRC.
