The points above are all correct--our distribution was simply made, and has its oddities--Q and H being the most notable (too many Qs / H is relatively easy to play for a large amount of points). Regarding the U/V difference, I personally think that using the same character lends Latin Scrabble more character, but I can see how that might not be popular. I do think one of the game's longstanding problems is the inclusion of Q without U, as there are no words, in Latin or English, which use Q without U (foreign transliterations for the purposes of selling scrabble dictionaries aside). If I were to redesign the set today, I would distribute it based upon Lewis and Short lexemes (as I understand you have), but treating QU as a single character, which would be on its own tile.
I have never seen a copy of the verbumsapienti set--when it first came out, I tried to order one, but they never responded to my email. I am running out of tiles to sell for our distribution and will likely not reorder them, so I would be happy to link to your game for people to continue playing.
I would certainly be interested in seeing your wordlist, and I invite suggestions for what material could be added to the latinscrabble.larkvi.com website, as it has been sadly neglected for too long. Articles on play or how Scrabble serves a pedagogical purpose are especially welcome.
