Shun the frumious Bandersnatch!
I can't speak for the Dragon, as I've never thrown one. The Archangel probably can't handle your armspeed, but there are a large number of kids and old(er) players that don't have that armspeed, and the Archangel isn't too bad for them. I'm one of the old people, so while my XT Archangel that I got years ago (and feels like a pencil eraser) turns and burns, my max weight DX Archangels are understable but go pretty straight on a hyzer-flip where good form is paid attention to.
And like I said somewhere else, if my DX Archangel is consumed by the DG gods in the lake, I'm not losing my beloved Champ Leopard3 or I-blend Sphinx.
Yeah same reasons I use a Dragon. However not a kid nor a older player, just a smaller adult player where 12 speed discs are as fast as I will go. I just need a way to reach the Dragon from the top of water when the disc lands there. I do have enough arm speed for a Champ Destroyer the 168-168 gram discs work best but when an open tailwind shot is available or an open shot I do not need to fight the wind at all I might use my Dragon as it's lightweight helps me to bomb the disc a long way if I am not hooking the disc on my fingers for some reason or the disc in my bag is almost worn out.
