I have an orange one that has a good dome. I saw three other red ones that were significantly flatter. One of the reds was flatter than one of my glow sentinels. Have not seen any of the yellows in person, but red seems to be the color to go with from my experience. Really liking this disc. It is a nice compliment to the 170 gram san marino in my bag, good high speed stability with a nice predictable fade. The orange Brinster in my bag is a max weight 180. Chained out on a 150 ft sidearm flex upshot the other day. The feel of the plastic somewhat resembles that of the sanny sentinels. Some of them do have a somewhat rough flash removal on the outer edge. This does not bother me but worth mentioning.
