According to "[My Little Wiki":](http://mylittlewiki.org/wiki/G1_Lickety-Split), the G1 pony's name is formatted as @`Lickety-Split@`.
I would put priority on the G1 pony for main tag as they have more images and are (arguably) more well known, while the colt can get (g4).
Or do it the other way around, it doesn't matter, but one needs a suffix even if they are spelled differently. I still think (g4) is better.
