I'd argue that if everyone's anatomy was identical, but I for one have pinkies that are 1.75" shorter than my middle fingers, making a 4 finger grip with proper alignment impossible.
Anatomy of your hand can indeed make a difference in how you grip a disc.
True, it can make a difference, however have you ever thought about trying to use the climo grip where you stack 2 fingers on the pinkie with the index finger tucked under the rim?
What about using a lower placement line on you hand to compensate for the difference in length.
Show me a person who "cant" and I will show you a person who "can", but just doesnt know how to yet.
My buddies own a disc golf store that i help out with and it never fails, there is always a way to make something work. I have reworked grips, throws, and general off theories that some of the local patrons have had. I could understand if you didnt have a pinkie finger, or if you were missing part of your pinkie finger entirely, but if you have functioning digit, you can make it work.
As for the person whose pinkie curls in towards their thumb, this is the goal of your pinkie anyway depending on the grip you use. Have you tried the feldberg power grip, only let the pinkie finger curl in instead of rest flat on the inside rim?
