Okay. Here's my typing on the KBP V60 with Browns.
Okay, here are my recommendations:
(0) You don’t generally want to be resting your palms/wrists on anything while typing, especially if you’re typing an extended amount, like pages and pages of text. Palmrests are great when you’re resting, but I wouldn’t recommend putting much weight on one while typing, especially since most palmrests are lower than they would need to be to support a straight wrist while typing. (There are probably some ways of typing while putting a little bit of weight on a palmrest that are fine, but it’s also pretty easy to slip into an uncomfortable way of using one.)
(1) Your desk is too high and/or your chair is too low. Right now, your wrists need to bend forward so that you can reach the keys, because your elbow is below the level of the table and your arm is reaching upward. The ideal chair/desk relationship will have your elbows at a 90°+ angle with your wrist at the same level as your elbows or even slightly below.
(1a) If you can, lowering your desk (e.g. using a keyboard tray) and/or raising your chair is the best solution.
(1b) If you are going to put your desk/chair the way you have them now (This is sometimes unavoidable e.g. at an office where you can’t adjust the furniture, or when working at a coffee shop, etc.), then you should try tilting the keyboard a bit more, until your wrists are straight. Having your wrists straight is more important than having your elbows open, which is why old typewriters and keyboards from 50 years ago have a steep angle: they were designed to be used with too-high desks. Moving the palmwrest aside might help to figure out a good angle
As always, let your own body be the guide. If something I’m suggesting feels uncomfortable or painful, then don’t do it. Do whatever you find comfortable and pay attention to what motions seem natural or awkward to you. Everyone is a little bit different, etc.
