And yet I didn't have any problems with a side by side set up as long as you respect the fact it is only an EQ6 with a claimed capacity of 18kgs which would be visual so imaging will need to be reduced some what.
(depends on whos specs you read) .

The 10"newtonian comes in at 10kg the wo66 a couple more plus cameras and guide cams ect and the side by sides. I did how ever put one larger weight at the bottom of the counter weight shaft reducing the need for extra smaller counter weights over taxing the thin shaft.
With just two scopes balacing was not an issue.
I originally had the guide scope piggy backed on the Newt and required an extra counter weight over what you see , so dispite the side by side weight it saved me a counter weight.
