Power up tried a few different blind structures recently they've settled with a 2k start stack and blinds of:
50 100
75 150
100 200
150 300
200 400
300 600
400 800
500 1000
750 1.5K
1K 2K
I think it plays pretty well.
Theres a big difference in 20bb play on PokerStars Power Up in comparison to normal holdem. It offers a lot of room for play ability
