Have you noticed much difference between the 2 stakes ? After looking at your other thread it is obvious that you beating 4NL consistently at a decent win rate over a proper sample of hands so I have no doubt that you will be able to do so at your new stakes.
If I was you I wouldn't even think too much in to what stakes you are playing and just class every game you play as BB's apposed to the actual amounts.
When I started out and moved from 4NL to 10NL I struggled mentally for a while for some reason thinking I had to play a different way now that I had moved up a limit.
I also tilted harder at 10NL for some reason, probably because I was used to having it all my own way at 4NL then when moving up I was getting in to a few more reg wars and getting challenged by the better players.
Even though I was still winning at the 10NL my win rate was not as high as it was at my last limit which also had some what of a mental effect on my game.
When I finally got round to thinking that no matter what stakes you play at it is still the same game. I managed to put the actual amount of the blinds out of my head and just class them as BB's.
I slowly managed to stop being so results orientated and stop being too concerned about my win rate and always checking my balance.
Since then when I focused on just playing the game and making what I believed to be correct decisions I have found it much more easy mentally for me.
Sorry if I have went a bit of track there mate, basically the point I was trying to get across is don't think too much in to it when you move up stakes. The game is still the same, fish will still be fish no matter what the stakes, and the reg's will just be players like yourself who have the skills and the bank roll to move up.
Try and avoid getting in to big pots with the reg's and just get in to good spots with the weaker players maybe squeezing lighter when you see a reg cold calling in position against a fishes open raise etc.
GL with your challenge and I will start following your other thread more closely
