IMHO these funny registrations become a bit of a liability, after a few years.
Also I note most of them are very hard to pronounce. I would always go for a custom reg (the cost is peanuts) and my choice would always be picked to roll off the tongue very quickly, without ambiguity. Unfortunately a lot of other people play that game too so the obvious ones have been taken
I saw G-BOLX a few years ago.
It's a lot easier to get these (ones which are 'suggestive' to an English speaker) in non English speaking countries.
