If we are talking about efficiencies, giving out two trophies is NOT efficient as some (most?) teams won't 'use' both trophies. Perhaps FIRST should give out 1 trophy at the event but allow teams to order the second one at a discounted price or free. This way teams that want the second trophy (to give to sponsors) can still get it while FIRST doesn't have to pay for the second trophy if its just going to sit in a box.
FIRST does already allow teams to purchase additional medals, trophies and banners here:
