Why don't you take your DSLR?I myself have a dslr, and need a camera I can take into sporting events.
Varanoid, it sounds like you may have the configurations wrong. Have Vignette process the photos in the background. Also, you may want to lower the resolution to fine or normal (I have yet to discern a huge difference and the files are a lot smaller). Frankly, they all use the same hardware so it's a question of how well they 'process' the incoming photo. I do agree with you that speed should be paramount so as not to miss a candid moment.
