ill probably go with the 20mb/s. the quality problem was when i was messing around with it in the house. it seemed like it didnt do so well in low light. i took a video with it mounted on my atv helmet and it turned out pretty good but im also going to be using it as a barrel cam for duck hunting and i want it to be good in low-light conditions also. thanks ill check those out and ill post up a vid showing the quality.
