I need some LRGB filters for my RASA- 2" mounted. 

The F ratio of the OTA is 2.21-I read that fast optics can play havoc with filters.

Does anybody have any experience of using LRGB with fast optics & more importantly did you notice any undesirable consequences when using the filters. I have the Baader fast narrow band filters but nothing is mentioned or marketed for LRGB so your observations would be appreciated.
