What Paradigm speakers to keep????

[Termdj]

Hi guys. I'm newly registered to the forum, but have been reading the posts for +- 6 months. I need your advice/opinion. Some background info..I'm in the process of building a new HT. I'm waiting for the building to be completed, so I can start doing the wiring etc. The HT room will be 27f long by 18f wide. In my existing TV room I have all the mentioned equipment in my signature. On the audio and video I started to upgrade my old equipment. I bought myself a Full HD projector(Sanyo PLV-Z2000) so I can have a 177 inch screen diagonally upgraded my old Monitor 9 v1 speakers to the new Monitor 11 speakers for the front. The sales guy lent me a set of ADP-390's for the surrounds to test for a couple of weeks. I currently have Monitor 9 v1 for surround speakers. Currently I'm in two minds regarding my surrounds. I read the posts regarding directional and Dipolar speakers and understand the difference but can't decide if I must trade in my Monitor 9's for the ADP's???

Why I'm confused..When I have the Monitor 9's connected I get a more "surround sensation" behind and on the sides from where I sit. I know it is more directional, but it is not distracting for me. With them I do pick up a lot more surround effects/noises. When I have the ADP's connected I get the hearing sensation of a more "spacious feel" to the surround effect. You definitely can't pin point the surround effects. With them I don't pick up as much surround noices/effect as with the Monitor 9's. The effects are more front biased then in the rear. The two different speaker setups do make a difference on the whole surround effect and I can't decide which to keep. Any help to convince me on what to do?
I forgot to mention that I'm going to buy a Anthem pva4 power amplifier to run the surrounds in the new HT room. If I keep the Monitor 9's I will be bi-wiring them and run the Infinity's from the Denon. If I take the ADP's I will run them together with the Infinity's from the Anthem pva4
