But, these are the most efficient way as far as leve allowances go. The triples appear to require 3x the items and give 50% of the experience of the singles, but when you turn them in, you get the option of turning in more items for more exp, up to 3x. Hence the numbers above. I am of the opinion that triples are never worth it.
To be fair, triple turn-ins are totally worth it when you need to be stingy on Leves due to having very few to work with.
