Great work Jack! Thanks for sharing your production with us. The variety of top styles you are making and the possibility of rules for one type of game seeds an idea for a side battle to complement the Ultimate Battles at some meetings. Certain current battles require an Alan Gray custom made battle top to ensure everyone has the same weapon and thus the battle is a demonstation of player skill. A complimentary battle of sorts may allow custom (or customized production) tops that fit within certain agreed upon parameters such as (but not limited to or including any of these) maximum weight, maximum diameter, limited material selection, certain launch techniques, etc. It might be quite interesting to see top geometries from different cultures but of comparable sizes in head to head battles of some kind.
Just tossing that start of an idea out there.
