Dynamic Head Movement & effects add-ons

[Kalnon]

I was looking to increase the realism up a notch and I am looking for things like more realistic dynamic head movement and other effects. I found three add-ons that seem promising and I was wondering what everyone thinks about them.

The first one I found is EZdok on Flight1 here: https://www.flight1.com/products.asp?vi ... d=ezcapro3
It has a lot of very interesting camera features and many effects like DHM, etc.

The second one I found is called Sim Physics here: https://secure.simmarket.com/fsps-sim-physics-p3d.phtml
It also has DHM and it also models much more realistic ground handling/braking, it says it takes into account the brake's temperature, runway surface type, and runway condition in terms of water-snow or ice contamination. It even simulates icing which I find very exciting. I know icing is barely modeled at all in P3D. The DHM effects can be disabled if desired so I could use the EZdok effects if they're more realistic.

The third one I found is FS Effects here: https://www.flight1.com/products.asp?product=fsstall
It models things like stall buffeting and engine vibrations, etc..

I also have a question, I do have A2A's Accufeel which simulates some of the same effects as FS Effects I believe (correct me if I'm wrong) so I would have to disable or uninstall Accufeel to try these other effects right?
