Thanks to everyone who offered their expertise, advice and suggestions. I'm going to buy a 7D MK II body to solve my most critical problems of buffer size and FPS. It will also help me in other situations so it will be a good investment and also provides a backup body.

Consider the purchase of a Nikon D500: I love the buffer on this camera, it can hold up to 200 images. Below is how someone described it on another site. I've never had it freeze up on me and I've shot wildlife with it many times.

From another website:
The "200-frame buffer" is only in Nikon's marketing material; it is a misleading claim. If you shoot 14-bit RAW, the true buffer is 29 frames. However, if you use a fast XQD memory card, such as a 2933x Lexar, the D500 can empty its buffer faster than you can capture images @ 10 fps. Hence nothing is left in the buffer. (Think about a bucket that has a hole in its bottom. As long as you lose water from the bottom faster than what you put into the bucket, nothing is accumulated.) 200 frames is merely an artificial limit Nikon puts in such that the camera won't keep on firing unintentionally. For example, if you leave the D500 on and put it inside a camera bag. If something squeezes onto the shutter release, it could keep firing thousands and thousands of frames inside the camera bag until either the battery runs out or the memory card is full.

Sounds great! While I have nothing against Nikon’s fine equipment I have been shooting Canons for 30+ years. So I am not likely going change.
