Uh oh!!!! Lol. But you've described it as well as I would have. I think ur right about how triple vowels are looked at.LLL.in King's speciality!
Any three of the following: A,B,C,D,E,F,G,H,I,L,M,N,O,P,R,S,T, would be classed as triple premium LLL.ins (although three vowels don't tend to be looked upon as favourably in my experience)
