"Digger" - Your name totally makes sense now!

Right on man, and Great video! I've gotta' agree.. you guys look like you have a lot of fun!
That's the only way to do things! Nice footage from the Mini, I'm getting impressed by those..
For a quad w/ such a small footprint, they really seem to stabilize nicely! No j-e-l-l-o.
A6500 - Great camera!
I've been shooting with Sony since they were Minolta! Love em'.
I use an A99ii, and a few A77iis. And an A77. Then too many lenses to even remember.
The A6500 and now the A6400 models look like really nice setups for sure,
and I was super tempted to get one. Only issue.. They're E mount and my gear is all A mount.
Sorry.. Camera addict.. lol Back to the subject at hand!
I think for what you're using your cams for - and where...
Going with another 7 would be a much better idea than to risk going with the 8.
If/when I grab a GoPro, it'll be the ol' lucky 7 also. Great features, and none of that nonsense.
