Boxer 9,
You have to find out first how does original rubber palm swell work for you.
I'm not a fan of palm swell, especially where my thumb barely hit magazine release.
I switched to LOK Standard and had a better grip and recoil management right away. LOK Standard feels a little better, you can feel that you get control over the gun.
I'm not sure how your thumb would sit, because your thumb shouldn't sit on grip at all
With LOK Thin grip you will see a big difference comparing to original palm swell (they are really thinner).
With texture you have to decide how you gonna use the gun. I use OWB holster, so grip doesn't interact with my clothes and aggressive texture works for me.
So my LOK grips are STANDARD FULLY CHECKERED.
- very similar felling to original (with LOK my gun sits better in my hands)
- no problem with sweaty hands
- the same C clamp over pistol grip (like with original) but easier access to mag release button
- and of course gun looks hundred times better with LOK
