Remember that SF puts function over appearance. The clip is a "Pocket" clip, not a belt clip. I've found the short one works good in the front pocket of Slacks or Dockers. The long pocket clip works best with the back pocket. Belt carry is discouraged. You have 2 options, short and long. When I first got the E2e, I couldn't stand the short clip either. After a few weeks of tryiing it out, I'll never go back to the long one!
The hex head adds strength and anti-roll properties (function over looks remember...then again, looks are opinion anyway right?).
The LOTC prevents acciedental activation in situations where your life depends on darkness. Also so it won't activate in travel bags, pocket etc. I've opened my bag to find melted lens' on my 9P many times, before they had LOTCs.
SF really is about making the best of the best sparing no expense. They put quality and function over anything else. I for one, like that.
