I recommend that you go with COG monolithic ceramics. They are very stable and have low dissipation and ESR. I would use the 100V one's in a 1206 SMT package for low stray inductance and series resistance while being easier to solder to than 0805's. Keep the resistor leads as short as possible to maximize the self-resonant frequency.
You can get then at Digi-Key for 50c ea.

Don't use film caps, they have tons more self inductance.
Have fun, Rick
