Is the kastan your after the kex? The one with the uni blade forks. Always wanted to race one of them beauts
Might be worth putting your list in the bmx chat section as some don't look in here, was offered a kex when I was looking for one off a top member on here but I declined when a bit of research revealed the down tube was a tad shorter than my xl tnt and it messed with my head
There is definitely a few different early to mid 90s clayborns (2nd gen and above) over here too,as I've seen at least 4 since about 2010 sell on ebay. from the second gen ones they changed the tubing configuration to the cross over and brace at the headtube which is the signature of every clayborn since.
I'm sure Jeff has a clayborn fb page
Nice list
