First, keep playing with your 3 lenses to find the optimum for those 3. I'm not surprised by your results so far.
Second, consider making at least 2 more and try adding them outboard of your speakers, then behind your listening position, etc. The outboard in addition to the behind the speakers positions (total = 5) may further tame reflections that are less important AND might give you a sense of greater width to the soundstage (though it sounds as though you don't actually need that). Behind you (total=5 with 2 behind you) might tell you more than the single one did, but I suspect it's about the third place most people would benefit, not number 1 or 2. Just a hunch.
As to the slap echo, that's where stuff like absorption helps. The little felt dots trick is neat and looks neat (if colored correctly) too and does something for slap echo, corner control, and if you extend them way across the wall/ceiling interfaces for those as well (but that's a lot of dots).
The floor is tamed by the carpet. If need be you can mock up a hassock/ottoman look stuffed with a bale of fiberglass - in other words a pretty version of JR's Q&D Bass Traps - then move them into position on floor. Some people like to tame the reflections of coffee tables, which seem to be placed at an inopportune spot for sound.
At some point I'll bet that either WAF or your own limits of taste will stop this stuff...
As to ceiling, you're on your own. Beyond felt dots I didn't experiment with this one.
