Sounds good Col
I'm really nervous about putting my GoPro in the air - even on the 550 given the nighmare I had with my first Naza V2. Seems ok now - but it will take a lot more 'air time' before I trust it again.
Never had an issue with the KK2's !
Also - have you seen all the new frames on the Hobbyking Global site - some nice FPV style frames on there like the DeadCat.
Personally I want this one (not hobbyking though!) :
