I was previously playing $25 NL with the 0.25/0.50 blind structure.
I decided to stay with the same structure, so I am now playing Party's $50 NL tables.
After 3 hours of playing, I would say that the $50 NL is slightly tighter than the $25 NL used to be; however, it is still extremely loose. I am having no trouble finding tables between 26-32% VP$IP.
The bad players now have more money to throw into the pot which is making me more money than I was with the previous blind structure.
Obviously it is too early to tell the exact affects this restructure will have; however, so far it has been extremely good to me
