That'll be fine Sword. The blue boxes will look better on the wall than those TS ones though.. :)

I do this with my system. I have 1x150/100 and 2x150/35.

It works ok, but because the three controllers are not truly networked, they do their own thing.

There was a post here a couple of days ago letting us know that all of that will very soon change (at least for devices that have Bluetooth)... true parallel operation.

Yea!
