For me at this point - Its kinda like that test you don't want to get back from your instructor....I really don't want to see all the crap I do wrong on a regular basis. Heck, the field I play at posts pictures and...I'm critical enough about my shooting form just looking at those.
I've thought about adding a camera to my eFlexes...I guess I just can't justify the cost.
Though, your marker should be "up" and in the direction you're looking, right? You should be able to identify that because your hopper isn't in front of your face.
