I'm starting to think having a few extra drivers is better than not having enough. There are always people who can't make races or would sit out to save money. Having actual crew is nice at races as well, we haven't had that in a while.
I don't think the experience thing would be a big concern for us, we're not arrogant and we don't have any freakishly talented drivers. If you have a couple HPDE's under you're belt you're probably within spitting distance of our skill level
We plan on going to a few driving events to shake the car down and can get a new person seat time.
I'm not really even looking for experienced drivers. The most important things for me now are having enough $$$ to race, and having time, ability, and DSM knowledge to help work on the car. Engineering types a plus.
Not too surprisingly, I can find a ton of people who want to rent seats and have always wanted to drive an AWD DSM in a wheel to wheel race. Just can't find people who can join the team permanently.
The goal with our car is to make it easy enough to drive that my grandma could do it. User friendly and reliable, as opposed to our last car (often would try to kill you).
