I have two EVO Premiums, normal for the right and Omni Throttle for the left hand.
The Premium grip comes with the center push assigned to swapping the mode of the analog stick by default. You can change the default mode in the software - I think POV mode is the default, and you can also disable the mode switching if desired. The benefit of mode switching is that you can actually bind four click actions plus two analog axis to that mini stick, but using the center click of the mini stick can get very fiddly in the heat of the moment. I never used the analog mode of my mini sticks and set their mode to POV and used them as regular POVs until the mini stick on my left VKB started bouncing signals in POV mode; then I swapped the ministick for the regular POV module on both my VKBs.
The tactile feedback of the POV module is much better than the mini stick's, and I am much less likely to misclick a direction. You also gain a more reliable center click. If you don't need or use the mini stick mode, I would swap it out.
If you need some reference material for binding, here is an older version of my bindings. I have changed some stuff since, but you will get the logical distribution of functions I used. YMMV though.
