of course! You always want to play against players that are worse than you (if your goal is making money)

You want tables with a lot of callers. If everyone starts folding when you raise, then get out. If your play is predictable, then switch gears, or switch tables. I used to have the same problem with building a stack, getting to a certain point, then loosing some of it. Then I learned about changing gears, loosening up when the table is tight, tightening up when the table gets loose, etc. However, table-hopping is not a bad strategy either, but when you have more chips, you have more leverage, and should learn to use it to your advantage.
