These floats just flat out ROCK! Keep em' coming!
I do have a few "user" suggestions for you to consider and for others if interested...
First - would it be possible to develop a glow version that's similar to the green? I often fish very early; before the light is on the water, so I bought some glow paint and painted the top 1/3 with a clear coat of H20 based PU spray varnish. Add 2-3 small glow corkies at the top as your float stop beads, grab your flasher and you are good to go for 3-4 casts. No batteries or glow sticks needed.
I'm just learning how to post pics here, so I hope these work.

Second - lots of us float braid and the floats can be very difficult to thread, especially in the dark with cold hands. Braid is just too limp to easily "push" through the float. So, I've made up (10-15) 2-3 ft" 30lb Mono "threaders" to assist the process. If possible, can a production threader be developed that's similar to a flytying bobbin threader, only much longer? See pics below for mono rigging and the cheap bobbin threaders for more detail.
Thread the mono up from the bottom, make loop and push it back through until it comes back out the bottom. Put enough braid through the mono that it will pull all of the way through the float (8 - 12"). Pull the braid through.
A longer "speed" threader would eliminate these steps and extra gear. It would probably need to be 1" - 2" longer than your current 30 gram float (one size fits all threader). You can purchase the standard bobbin threaders shown in these pics in (3) packs for about $4 dollars from any flyshop. I think a (3) pack of Cleardrift "Speed" threaders would be the SHOW!

Anyway - hope the above is useful! Tight lines,
