Thank you for your comments and suggestions.
I have used the eyepiece + Barlow combination with variable success in terms of quality (usually 15mm + Barlow). It's never been great (but then again its the equivalent of a 5mn piece). I would say, my 6mm GSO consistently gives me a better picture than the combo.
I wonder then how some of you manage to use CCD + x5 Powermates on planets with such great success!
Cheers,
Eric
