which barlow for planetary

Hi All,
Just a quick one.

I'm looking at getting more scale out of my scope for planetary imaging
8inch f/6 on eq6pro
spc900 cam

what is the best barlow / powermate?

i've currently got a 2x barlow

would a 2.5 powermate or 4x powermate be a next logical choice for this setup or will 5x powermate be useable ?
will this simply make the image too dim for this aperture / camera combo?

at some stage i do plan on upgrading the camera

any suggestions would be great!

Dan
