Thanks AndriaI'm not sure about actual beauty rings that can be bought, but on my flat-top V3 which isn't *really* flat, I use one of the kayfun rings in place of the regular top cap; it doesn't screw in or anything, it just sits there and the tank holds it in place -- but, it's just a smidge (a tiny smidge!) too tall, so if the tank you're using won't let you extend the 510 screw a little, then it won't work. My Tobeco KFL+ tanks let me extend that screw without loosening the coil block, so it works great for me.

I've been reading your posts in this huuuuuge thread and saw that you were looking for the same thing as me
I'm glad you have sorted your issues
I have emailed segelie...if I get a result I will be happy just to have the flat top...I guess the round top only looks good with smaller tanks :-(
