In my opinion a 10 inch SCT would be too much weight and focal length

then some.
Which is not to say that it
cannot be done. But it's not a turn key affair. It would help
considerably if the G-11 was in an observatory and out of the wind. But
in a portable situation this is harder to do.
My G-11/Gemini was turn-key. Bought it, installed it in my observatory,
did a drift alignment, and was off and running. That has been the
experience of every Losmandy mount owner I know. And isn't /every/
equatorial mount easier to use in a permanent installation than on a
portable tripod that is put away after each use?
FWIW I had a C-11, Van
Slyke Focuser, ST series Camera and a guidescope and ST-4 guide head in
my observatory. Sometimes it worked great. Other times the guiding was
less than what I wanted.
Then it doesn't sound like a mount issue.
But to be perfectly fair this was a *lot* of
payload. At the price that I had invested in the setup I was happy.
That was on a G-11?
The Takahashi has, IMO, better (lower) periodic error and they are much
less trouble to fiddle with.
I've used the Tak mount only briefly, but I was impressed. How long
have you owned EM-200? How much weight is it carrying? Would you buy it
again?
Take a look at the AP900 Mount or the newer one that they have out...
The OP says that a mount costing about $4k will be "a significant
investment" for him, and you're recommending a mount that costs $8,000?
