Ergo, I'm really interested in the HUD, although, like you, I'm having some trouble thinking about whether it fits my "mission"--which mostly involves flying low and doing water landings for the fun of it, ofen with other seaplanes. I'm almost always looking outside the cockpit for that stuff.
On the other hand, an iFly HUD might be useful on trips or in lousy weather. Or at night. Or possibly when there's a lot of ADS-B traffic nearby. Or for other occasions that I haven't thought of yet. So I'm curious to see it in action. Unfortunately, I haven't come across any PIREPS yet.
