The field of Nl16z is much more difficult than the field of nl10z? Or they have almost the same level of skill, and the same win rate made in nl10z can be made on Nl16z? :hmmmm2:
Normally the next level up will not be too big of an adjustment, but realize any time you move up your competition will likely be more experienced and aggressive.
If you are winning consistently at your level and want to win more then taking shots at the next level is not a bad idea (but be prepared to drop back down if it does not go well).
