I guess you are talking about DSA PBT Blank keycaps.
They are "okay", not really thick but thicker than DCS. PBT caps tend to be slightly bent (if you are extremely anal about these things), ABS shrinks less when it cures so the keys look "sharper".
Poker 2 keyboard has pretty standard layout. Alpha+Mod and you are covered (with plenty of spares).
Regarding the landing pad, you can't really see them... unless you look at your keyboard at a really extreme angle I guess...
