1D classic vs. T2i for indoor sports

I have an opportunity to be a 2nd shooter for an indoor soccer (futsal) tournament in November but am not much of a sports photographer. Actually I have practially no experience as my interests are predominantly landscapes, architecture, and macro. I have a 1D classic and a 550D (T2i) and don't know which I might practice with between now and then to produce the best results. I only recently acquired the 1D and have yet to appreciate all it has to offer. Any and all input or comments would be greatly appreciated.

Q1: Because they represent two very different eras and DSLR capabilities which would you use for shooting this event and why?

Q2: Since this kind of photography has different lens requirements, which of the following lenses would you pair with the body selected above?

Lenses I have available are in my sig/list below.

Why not use both?

Ill probably combine 1dc with the 85mm and the 70-200mm with the t2i. I get a max range and a intermediate zoom without having to change lenses.

Thanks Mike. I hadn't mentioned that I have a 100-400L on the way. Would you use this over the 70-200 for the "max range"? Would you still pair it with the T2i for ISO/resolution reasons or pair it with the 1Dc for the AF knowing that you're giving up res at a longer range?

I would be concerned about the lighting, unless you're allowed strobes. I would use which ever body gives the least noise at high ISO.

You mention that your main interstes are landscapes, etc.. So were mine. I had no intrest in sports but now I shoot for several teams, It's addictive, just as photography in general is.

Not from an indoor event, but here are actual pictures from a T2i taken at a night sporting event illuminated by floodlights and at high ISO.

Thanks for the visual DC. If you had to shoot this exact same event again with the T2i and either a 70-200 f4 or 85 f1.8 which would you choose? My sense for light is not good enough to know how your shots would come out without the extra stop.

1d has crappy high iso (in today's standards), but iso 1000 is still very useful. 550d has most likely good high iso, but af is useless for sport. So in my opinion only option to go is 1d. It's better to have some noise then photos that are not sharp. Even if you would use both bodies, go with 1d for long lens. Af is much more delicate on long lens then on wide angle lens.

Thanks Primoz .. this helps me pair them.
