Sure. Think about your kit construction. What you want it to accomplish? What you shoot? What are you missing?

From my standpoint, you seem to be creating a casual zoom kit (24-105, 100-400 II) that will work for most of your photography and augmenting that with a few fast primes for specialty purposes.

Or, from what you've said, I could see you pivoting to a basic "faster" kit. One of my favorite forum member kits for its simplicity was Rokinon 14 mm f/2.8, Canon EF 35 f/1.4, and Canon EF 70-200 f/2.8 II.

As you like eagle shots, you'd also need something longer, such as your 100-400 II. But that above kit can take a lot of amazing pictures.

Lots of options. Lots of ways to construct a kit. And while I really do love that basic kit, I have gone my own direction.
