Yes, ladies and gentlemen, I am here to inform you that keycaps can totally transform the feel of your keyboard.
I'm typing on KBC PBT caps on my Filco with brown switches right now and for the first time experiencing the awesomeness of not bottoming out.
Honestly, I was a bit disappointed when I first got my Filco because the ABS keycaps made it feel cheap. If you think you are satisfied with the stock ABS caps that came with your keyboard, try PBT, Doubleshots, or POM and you won't be disappointed. I really didn't think it was going to be this big of a difference changing just keycaps. The board is totally transformed. Just a quick informational thread for anyone who is on the fence about buying new keycaps.
They really aren't even that expensive if you play your cards right in the classified section. I ended up paying a total of about $7 to trade stockies for PBT's. Right now I'm rocking engraved black everything with an orange Geekhack Doubleshot Escape key... have plans for other color combinations later.
