I just did mine today. Defiantly the right choice. The OER pad has a few waves in it, but I hope the summer heat will help it relax. The VA center vent looks out of place and cheap. The one thing I did was all of my ductwork I put HVAC silver tape around with a zip tie. It would suck for it to come loose. May be overboard, but I feel better.
