I have the same helmet. Super nice but heavy, but still love it. On this helmet I use the Sena 50R, works fantastic.
On my original Neotec I first used the cardio which we did not like at all on long trips or anytime.
I then changed. to the Sena 20 it was very very nice and used that for quite a while and now with my new Neotec II, like yours i use the center 50 R.
