If going Dynon you need the newer Skyviews. I have twin Dynon Skyviews and they are just fine. As you say the older D100/!20/180's were a problem under a bubble canopy.
My preference would be Dynon Skyviews or GRT Horizons. Only issue if going GRT is the lack of a UK/European agent. Garmin stuff is ok, if expensive, and you end up with Garmin Pilot mapping which again is silly expensive on chart updates.
