Two very good reasons to use MAX:
1. If you don't, and you go off the end, you'll carry a heavier can;
2. Achieving an accurate touchdown all flaps up is not easy. The handling is very different, and line pilots rehearsing in the simulator often overcook the flare and float quite badly. Reasons for this are the lighter stick force at high speed clean, and the powerful visual cues from the high ground speed. (Tip: if you have to do this for real, aim for a very slight nose up pitch input, and ask your P2 to guard the control column from more than about an inch of rearward motion in the flare).
Very few pilots get to land all flaps up, and the odds against having to do it on a limiting runway are so great as to suggest that there is no real reason to ponder too much on this particular topic.
