What do people think of the 5d as an indoor sports camera?
Quite possibly a stupid question, but i had to ask.........
I know that it's not what it was intended for, but i shoot a lot of indoor showjumping and find myself shooting more often than not at iso1600 resulting in a lot of noise!..... It seems to me that the low noise levels of the 5d at iso1600 and 3200 would be highly beneficial to me..... maybe more so than the 8.5fps of a 1d mkIIn..... is there a major difference in noise performance between a 5d & 1d mkIIn?
also how is the performance of the AF on the 5d for sports in AIservo? i'm sure it doesn't compete on the same level as the 1d in that respect but is it better than say the 30d??
What are peoples opinions on this? It will be summer before i'm ready to make my final decision but i'm trying to gather as much info to help me make my choice when the time comes. It's a lot of money to spend so i really need to make the right decision as i won't have that much spare cash lying around for a fair while after!! anyway, please help.... this whole thing is doing my head in! 

I don't think the decision making would be made any easier.......... grrrrrr
