I have an odd motion with my shoulder more then anything else. I don't "load it" straight down, instead I do a roll (Bring my elbow over my shoulder to load) It doesn't really do anything different as I get decent pace / accuracy with it. I've had a few coaches say it's totally fine, but it does look a tad more awkward compared to a nice pin-point load up.
