Honestly, I feel like “Yeti” is too cartoonish and won’t be memorable (in an good way) after a few years.
I like the flexibility of “Spikes,” but I agree with others that have said it’s probably better for baseball. “Gulls” Is kind of in that same realm for me.
“Black Diamonds” is cool, but the reference to another specific winter sport feels forced.
Of those listed, I probably like the idea of “Swarm” the best, but it’s somewhat anticlimactic (like “Minnesota Wild” or “Atlanta Thrashers” or “Winnipeg Jets”) even with the local area reference, so I’m torn. I think that one could at least grow on me over time.
The others are mainly forgettable to me.
