Any of you guys running a GoPro, what external mics do you recommend? I just picked up a white edition for $45 off (no Black/Silver nor Contour were available) and was wondering what's given you the best sound on your videos? I'm looking to use the GoPro on Friday @ LS for a Jaguar track day (driving the F-type V8 S, XKR amongst their offerings) and I'd love to have the GoPro dialed in for it. Furthermore, for the Do the Screw event in August. Thanks!
