I agree with David. For fast action you need a DSLR. For
high speed you need large pixels and low noise. Look at the
latest issue of Pop Photo where they tested a bunch of DSLRs.
The Canon 20D came out on top, and I bet you would get much
better results from the 20D than you do with iso 1600 film.
For true professional fast action work, the top end camera
is currently the Canon 1D Mark II, imaging at 8+ frames
per second. The new Nikon D2X might be a contender
too, but I haven't seen reviews yet.
ISO 1600 film is only about 3 to 4 megapixels digital
equivalent, see:

but DSLRs have higher signal-to-noise ratios:

and DSLRs have higher dynamic range than film.
The DSLR pixel size advantage is important for work like
you do, see:
