Mount option for 10inch SCT

[catburglar]

The hand controller for my 10inch LX200 has developed a fault - the direction buttons don't move the scope (although the motors still work when I start the alignment process). It may still work with a computer control to move it, but I was considering switching it to an EQ mount anyway, so this might be as good a time as any. I'm mostly visual/EEVA and liked the convenience of AltAz mounting, but I had a disappointing experience with an AZ-EQ 5GT (with a smaller scope)- there was too much play in the AZ motion so I was never really happy with it, so don't really want to try my luck with the AZEQ6... 

What's the sensible option- EQ6R? It's rated by the manufacturer to 20kg...I haven't weighed the OTA, but I read that they're about 14-15kg.

I like the look (stiffness more than tracking accuracy) of the harmonic mounts, but I guess I don't really need the portability and the smaller ones are rated to 13-15kg so I think the scope may be pushing it a bit.

Ioptron also have CEM and GEM mounts in the 40-45lb weight class, but they seem a lot more expensive and I'm not sure they add much over the EQ6-R.
