I can't use the older change-X sign because none of my friends, at least the ones from the West Coast, use it. When somebody does use it, I find it disconcerting. Generally, I use the new sign for TRANSGENDER although I "re-open" my dominant hand after I close it. Once I showed it to my friend, a native signer of Taiwanese SL, and he thought it resembled a blossoming flower.
