A summary of the Major Cherry MX Keyswitches:
■ Cherry MX Blacks: 60g actuation force | No audible feedback | No tactile feedback
■ Cherry MX Reds: 45g actuation force | No audible feedback | No tactile feedback
■ Cherry MX Browns: 45g actuation force | No audible feedback | Light tactile feedback
■ Cherry MX Blues: 50g actuation force | Audible click | Strong tactile feedback
■ Cherry MX Clears: 65g actuation force | No audible feedback | Light tactile feedback (but more than Browns) | Not very common
■ Cherry MX Silents: Currently only two kinds: Black and Red. Properties are identical to their normal counterparts, but they have a shorter travel distance (3.7mm vs 4mm).
Actuation force and Activation point: Activation Point is the key travel distance where the key is actually recognized by the keyboard. Actuation force is the force required at this point. Put simply, it's how hard you have to press the key for it to be recognized.
Tactile feedback: Sometimes referred to as 'tactile bump'. Tactile switches have a (sometimes subtle) bump you can feel in the key press before bottoming out. This bump typically represents the actuation point.
Travel Distance: This refers to the actual distance the keys of a keyboard have to be pushed down before the keystroke is recognized
Audible Feedback (Or whether the key is Clicky or not): Clicky switches make an audible 'click' when typing. Clicky switches are typically preferred by typists, but are noticeably louder than other mechanical switches. Use with caution near noise sensitive co-workers or spouses
Now that that's out of the way, I'd recommend you try out MX Blacks if you're having trouble with pressing multiple keys. They are harder to press down than MX Browns. If you want to preserve the tactile bump you feel with Browns, try Clears as well (Although both Blacks and Clears are relatively hard to find. Clears especially are only available on very few keyboards). I have an ASUS Strix Tactic Pro with MX Blacks, and certainly you can feel the difference; the keys are markedly harder to press. However, keep in mind this means that you are more likely to experience fatigue when typing for long periods of time.
The best way to see which key is for you is to order a Cherry MX Switch Tester:

You can ignore the MX Greens, as they are virtually unused for standard keyboards. Test each out and see which you like the best!
