hmmmmm. i would go the eq6 over the eq5 clearly the larger mount gives you more options long term,
mount mount mount.... if it lets you down its a bust.
one also needs to consider aperture fever, it strikes many and its nice to have a bit of back up room to expand and update.
me i bought the G11, could have used he titan though ... never mind if i had one of those i would have only put a 16 inch or bigger on it and wanted the next mount up
