Hmm. In my pronunciation, there seems to be a vowel before the "n", at least when I articulate carefully; but {trstn.} is perhaps closer than the alternatives. But doesn't it then end in a vowel? Or do pseudo-vowels not count here? Probably not, as they never occur in gismu, cmavo, or lujvo. co'o mi'e dilyn. (Hmm. Perhaps that should be {dil,n.} No, I don't think so.)
