We are thinking of taking the plunge and buy a high end device. It is still some time away, and a little more experimentation and familiarization with the lifestyle using the CB6K and similar devices will probably ensue for some months, but being a nerd I am looking at alternatives. My wife and KH has a clear set mind about aesthetics, so after running some alternatives by her (all Gerecke titanium models were shot down...) she has taken a fancy to the Crossfire from Steelworxx.

I see some members of the forum have used this, so I hope there are some with experience that might be willing to share a little insight. All other observations are also welcome

So to my questions: Is the Crossfire suited for uncut users or will the foreskin bunch up in the head and stand the risk of getting pinched outside the cross? I have some problems with this on my current CB6K, but my wife does not want a fully closed design. She wants to be able to tease, and also there is some qualms about cleanliness in a closed design.
Then there is the option of the urethra plug from Steelworxx. Has anybody fitted this option to their device? Is it possible to specify like the plug on the looker? Does anybody know if there is a possibility to fit a plug onto a device in a manner making it possible to remove the plug, but not for the wearer while wearing the device? As an engineer I see certain possibilities for this, but they might not be commercial. I have read Thumpers debate on any device being prone to escape, but with the rod and solid sides this setup must be quite safe?
Finally I wonder if there is anybody out there who have tried to bend a split ring to make it anatomical? If so, how did it turn out?
I hope there are some wise men (and women for that sake) out there that are able to help me along this path
