Polarizer filters for wide angle lenses

I've spent about 3 days reading every post I can find with regards to polarizing filters and would like to ask for some input from others.

I have narrowed my selection down to Hoya filters.

I have the Canon Rebel XT, Canon 28-135mm IS lens and am going to buy a Sigma 10-20mm lens for my wide angle.

My question is, which filter should I get? I figure that I should get a 77MM filter and a step-up frame so the filter can also fit on my 28-135mm (72MM) lens.

Which of the following would be the best filter for my setup?

1) Hoya Pro-1 Digital Camera Circular Polarizer

2) Hoya Pro 1 Super Multi Coated Circular Polarizers

3) They also offer an ulta filter which I believe is thinner than the others (3mm as opposed to 5mm).

Or, considering the lenses I have, am I wasting money on higher end filters and could get the regular HMC filter.

Thanks for the help,
Jim

The Hoya SMC is usually the best for all-around usage. The Ultra-Wide, however, might need a Thinner Filter to prevent Vignetting - I don't have experience with this, so I'll leave it to someone else to confirm or deny this.
