The blades on the Medium and Large are the same size, but the blade on the XL's (XXL's also) are approximately 3 1/2" longer.
Most folks that I've heard who could wear both preferred the XL over the L, due to the greater surface area available for propulsion, but some really like the short blades for tight spaces (like wreck penetrations)
Aloha, Tim
