No I haven't. Just eyeballing that option it looked like the depression was too high and I'd have to prop the helmet up. I'll give it a look. Thanks.
I was hoping someone would say this (although with a little more detail). Do you turn the helmet backwards so the cradle (and Sena) are on the inboard side? What size is your Neotec?
A top box is out of the question. I'll look to see if I can use a Guardian with my rack for those times when my panniers are otherwise occupied.
Thanks for all the suggestions guys!
I put mine in the RH bag with the Sena facing Left or inside. My Neo is a Med I think.
