High Quality Keycap Replacements for Backlit keyboards?

[wetto]

I recently bought these keycaps made by Vortex, which are very well done IMO, but aren't fully compatible with some of my keyboards and the font itself isn't really all that nice.

Since I'm a reviewer, some companies send a few keyboards to every once in a while, and if there's a common trait between 99% of all gaming keyboards, is that their keycaps are bad.



1. Solid Year (Logitech G710+), these are crap.
2. iOne (Tesoro Lobera Supreme)
3. Costar (CM Storm Trigger), this is the most decent one, besides the Vortex.
4. Vortex (Black Translucent PBT+POM Double Shot Keycap Set)

Since I'm actually new to the keycap business, where should I look for quality translucent keycap sets besides the Vortex one (which I already have) to replace whatever keyboards I come across, especially boards with 1.5/1/1.5/spacebar(6X)/1.5/1/1/1.5 modifiers?

I know Ducky sells their Shine keycap set (http://mechanicalkeyboards.com/shop/index.php?l=product_detail&p=1165), but is there anything else?

I would only use the Vortex ones or the new Leopold / Max keyboard / whatever doubleshots: https://geekhack.org/index.php?topic=72569.0

They're decently thick and both the white and red versions let light through the legends, but not the bases.

I just use thick SA doubleshots on all my boards. I like the backglow I get from those, don't need to have the light shine through the legends, since if you're using your PC in such bad light that it's necessary, you're not doing your eyes any favours. Backlighting is only for posing your board for photos, IMHO.
