The debate is drifting a bit imho in the last few posts above. This is, imho, not a battle about which is better out of hydraulic or electric. Both are perfectly fine inho, and in BartW's case electric is preferred becuase of the easy fitting. Nor is it a battle about CMC vs others - there are many good respected manufacturers including CMC.
As I see it, this debate is really on 2 points:
1. whether there is something so magical about electric that it permits use of 60% of the fin area of a hydraulic system. On this point, CMC seem to say the "magic" is faster acceleration of electic fins. I'm very sceptical on this and have put it in the MBS camp. There may be room for more debate on this! BartW doesn't much care becuase this point only affects zero speed stabilisation not underway, and he would I think even be prepared to accept a trade off there for the much easier install of electric
2. Whether there is any heat problem. I've said all along on this that there isn't any heat problem so long as the heat generated can be disipated, and that's easy enough to check by exaimining a system in action. CMC seemed to say there was little heat because the gearbox is like a swiss watch. That isn't even suspected MBS; it is fully certified MBS, though the heat generation in an electric system producing high forces and doing no work seems less intuitive than I thought (see electromagnetic crane discussion). But anyway we should park the heat problem because BartW can check it straightforwardly and we have zero data about disipation ability in the system

. In maybe 40 years when we are both in an old people's home they will put in our own soundproofed wing of thebuilding so we don't distrub the other patients
