Vexed- as an FO I do (subject to Captains objection) request visuals on every approach, and if denied, I'll fly manual raw data on 90% of my landings, as soon as I pass the IAF (don't want to hold raw data- too much effort). The only captains that deny it, don't blame the OFDM, they try to cover up the fact that they can't do it themselves, so don't let an FO do it!
