Paul, I was wondering the same thing a few weeks back until a few
people put me straight.
You do seem to need the IR filter in combination with the RGBs because
the RGBs all have a second spike of response up in the IR which needs
to be blocked.
If you read this thread:

.....Merlin, from the UK, has a spectral response
curve set for the Meade filters he can PM to you.

hope this helps,

Steve
