Anybody got any good suggestions for suitable fitness tests for uwh?

I am quite familiar with the Beep Test, but I find it doesn't show enough differentiation at the high end - ie all top performers tend to get very similar results +/- a couple of lengths. I haven't really done it myself much - time consuming/ requiring others / painful - so don't have any "before & after" results to see if there is much individual improvement.

I know there is no one perfect test, so we are going to need a battery of tests to cover various aspects. Any suggestions?
