Piper also do a gentler cam - 255/264 or something like that which has duration half way between standard and 270 IIRC (go look at Piper's and Kent's websites - all the data for their cams is there in the PDF catalogues - basically you can compare them on duration and peak lift - obviously the shape of the cam makes some difference, but more-or-less duration and lift give you the story, with duration being mostly responsible for lumpy idling, especially when you set the cams up with quite a bit of overlap).
There is also a rover 135 cam which is a bolt on to the standard 1.8 K16 to give it about 135 BHP and IIRC, it turns out to be the standard VVC exhaust cam IIRC. This cam was fitted to some variant of the MGF and might well be a good compromise cam. PTP sell what is probably the same or very similar cam that they call the 140.
If you want to see what 1811 torque curve looks like, search back for hiscot's R/R (at the wheels) chart from a while back.

You'll see that has power rising all the way to the red line and plenty of torque to boot across the range to 5,000 RPM (compare that with your own at the wheels figures which you might have somewhere on your chart). Of course that car has TBs etc., so not directly comparable, but shape is good.
BUT I think any cams plus the headwork on your engine will take it close to the edge for the MEMS - that's not to say it won't work, but it might be border line in a few places.
