Yes. I find it works much better as I'm only sending the trigger. Zero lag, does take a little longer to program but it's only a few extra minutes per remote. Always done it this way and don't have any issues. That 7000 sq ft house has 2-MSC-400's, 9-MX900's and a MX980 controlling 12 TV's and a projector with 4 cable boxes and 6 satellite receivers. For 9 of the TV's we had to use the ir out of the remote for turning them on but everything else is a trigger. Haven't had a single issue in over 2 years and even from the top floor controlling the receivers is instant.

With sending an IR over RF it's a longer command. The triggers are short and fast. When I took the training with Jeff years ago this is what he had suggested and have been doing it ever since. If we had wired the house all the TV's would have been controlled from the MSC's but in this case we couldn't as the original installers didn't run the proper cable.
