I started doing the same.
I was as well, until the 8a (16 burst) starting coming standard on the gecko rx (65a and up I think). That seems to be enough insurance for me
I'm using just the gecko internal on 60" birds and down without a blink, and Brian is using just the gecko on his 71 Extra.
For those who like external, check out ZTW's new 12A BEC:
