I've been on the fast ring for a while now on my Icon. Wondering whether there is any advantage to downgrading to 8.1 and upgrading via Verizon's W10M release? Phone seems to be running quite well on fast ring for the last couple of releases, with the exception of a (I've heard) known issue with the BT LE driver that screws up notifications to my Garmin watch. I just hate the idea of going through the whole downgrade/upgrade/setup process if there isn't any real difference. Has Verizon released any firmware update to go with their release?
