Customization Questions, Any Input Appreciated!

There are so many ways to customize the Cyborg, but I don’t want to waste money. Here are some of my questions:

1. How does the flat and curved palm rest differ? Ive heard conflicting information about which one is better, so in terms of how they feel, what do they do that’s different?

2. Does the elite thumsbtick adjust to lower tension than standard? If so, is this difference significant/can feel increase in speed in rapid movements?

3. Is the stand worth it? Does it actually make a difference in long term comfort/usability? Any disadvantages?

4. Grip tape. I normally put grip tape on most of my peripherals. Is it worth it on Cyborg as well (palm and button tape)?
