Update, resolution of sorts:
I went to the local shop and picked up some plastic...
I played a round using these 5 and also did some fieldsies.
Kaxe is my new bff.
Compass is a nice neutral glidey mid that is great FH or BH.
Wasp is nice, a stable buzz, but I won't be throwing it. I wish I would have bought another DD2 instead (oops). High quality disc, maybe I'll change my mind. I've thrown a lot of Buzzz and bag a Meteor.
Bullfrog was surprising. I like the feel in the hand but the flight has it earning a spot in the bag. It does something slightly different and it's hard to explain. It's like a Pig that hunts out neutral but has a vague anti-fade to its fade.
Berg reminds me a lot of my seriously beat-up Banger, but doesn't fly as far by about 10%. What a cool disc.
These recommendations (Berg I just got on a whim) were all solid because they are each are capable of a high-torque laser shot that lands generally flat.
On a particular hold at my local course I told myself to pretend the disc I was about to throw was my DD2. 'Just execute exactly as you would with the DD2.' What I discovered is that either (a) I'm naturally throwing my DD2 on hyzer, or (b) these mids are too flippy for the energy used. There is clearly an archer/arrow aspect to it. But I trust that DD2 shot like a sniper trusts a favorite rifle. I hope you can relate--there's an ergonomic aspect to this problem. I have to do something slightly different with one of these mids/putters in my hand and with my throw.
Maybe. Idk. This whole affair is honestly confusing, but I'm looking forward to figuring it out some more.
Super impressed with that Kaxe tho!!
