They both seem to be the same. I tried both, returned the FV1 and have a Bauer one in the garage since I picked it up used, neither was long enough for me. I wear a large Bauer Profile III cage (CCM cages I'm between a medium and a large which is why I go Bauer for cages). I'm the same as you, wear a small CCM helmet (or medium Bauer) but need a large cage. I was able to wear the Bauer bubble for a couple of games but it just didn't feel comfortable since it was a touch short.
