I recommend more aperture. Even with the best quality eyepieces, you can't see stuff if you can't get it bright enough to you eye. Filters, while enhancing contrast for better visibility only reduce the overall throughput of light.
From 8 to 12 inches you more than double your light gathering power.
My 12.5" dob is significantly brighter than my 10". My 18" is much much brighter than the 12.5"
As you have noted however, mobility becomes an issue as size increases. Only you can determine if you can handle a larger sized package.
(I now have aperture, I just need clear skies to view through!)
