I can't wait to watch Tomac race in the 450 class this weekend. At the same time I've got to agree with flug. Its just seems like poor structure for this racing series. You should have to stay in whichever series you started in.
Even though no one cares much about the back markers that barely make it into the main every weekend you still have to think about them. With Tomac in you're taking away someone else's paycheck by getting into the main. In F1 a GP2 driver can bump up mid season but he's got to drive a car thats already registered in the F1 series. It would be like adding a 25th car on the GP grid if it were the same as supercross.
If a 450 rider gets injured I wouldn't have any problem with a 250 rider filling in for him. Simply adding someone else into the mix mid season just for the hell of it just doesn't seem right at the pro level.
