Flying Mounts, post 310% thoughts

Got myself a http://www.wowhead.com/?item=43951 today!

Culling of Stratholme was the daily heroic today, and I'd not done it in months. Last time I did it, casuals were in lvl200 epics, and actually wiped in heroics. This time we got the timed event done with about 10 minutes remaining. EZ mode. And I was the only one in the party without the Bronze Drake!

However... A couple of weeks ago I got myself a nice shiny http://www.wowhead.com/?item=44177 which is 310% speed. Like about 5 other mounts in the game. Since I see myself getting none of the other 310% mounts in the near future, it kind of limits me to what I can fly. There are a huge variety of other groovy 280% flying mounts, even just different colours of drakes and proto-drakes. But I'm pretty much limited to my big pink dragon for a while, or else go 30% slower than I could be going. I guess even the rare 280% mounts now also only count towards my 100 mounts achievement. Alas!
