Most discrete chastity device?

I've got a cb6000, which is good - even for long term use. But, I suspect it is possible to see the bulge, maybe I'm imagining things? Anyway, what would you people recommend as the most discrete chastity cage? And, what is the most comfortable long term chastity device?

Jail bird from maturemetal fantastic device
Droopy and Miss

Another vote for Jailbird. Had a 6000s and this one is so much better. Be sure to measure very carefully - the bettter the measurement, the better the fit.

birdlock hands down

Another vote for the MatureMetal devices. I have the Queen's Keep , which is very similar to the Jailbird.

I like to show a bit of A bulge,....makes me wonder if people know i.m in a chastity device, quite exciting really.
