I debated purchasing an integrated comm for my first nice helmet, a Shoei Neotec. I am glad I went to a standalone unit instead. That helmet did not end up working out for me and I was able to move my comm to my next helmet. Otherwise, I would have been stuck with two very expensive paper weights.

I'd say go for the cardo, if you have any buds who you'd ride with, go for a mesh one if you have the budget. Freecom is a good pick if you don't think you'll connect w other riders much 👍
