Difference: PP .50/1 (6Max) vs. 1/2 (6Max)?

[DerFleischmeister]

Other than "I pwn .50/1, 1/2 pwns me", what major differences have any of you who have played both of these limits consistently noticed? While bonus clearing today at 1/2 6M, I finally had my first positive session EVER (and it was +7BB over 500 hands...not exactly crushing the limit.) I have noticed SLIGHTLY more aggro, but there seems to be something more I'm not getting. I have similar stats for both limits (roughly 24/16/3, sample size too small for both limits), but apparently there's something different going on at 1/2. I'm pretty sure it's holes in my play, as opposed to just running bad, too.

What I'm looking for here is general differences between the two limits. Then, I'll take this info, analyze my play, and post specific 1/2 hands I have questions about.

I'm posting this here vs. in HUSH, because we all know that the HUSH crowd doesn't acknowledge the existence of SH below 5/10...hence, I post in the micros.
