PokerStars Heads-Up Freeze Outs

[HuggyBear]

I have recently played a few Heads-Up freeze-outs on Stars for fun and very short term success. I have played 5 +.25 and 10 +.50 NL Hol'em. Each player begins with 1500 chips with the blinds at 10/20 raising every 10 minutes. My questions are these:
Are these freeze-outs profitable?
If so, does anyone have any extensive experience with them?
Any other thoughts?

I play the limit ones, but just to unwind. They don't seem as profitable as other games.

Are they profitable? Yes, of course.

How profitable? Probably not very. I don't think the edge you can gain is too much. A very good player probably can't expect to win more than 60% of his matchups, maybe even less.

I made a very similar post yesterday. I played a few of them and pwned some n00bs but I don't like stars software and the increasing blinds very much.
