I went from a MS FF2 stick to a CH Fighterstick and my gunnery improved.  Not to say the MS FF2 is a bad stick.  But, the fine control of the CH Fighterstick is noticeable from the FF2.   
The CH Fighterstick does take a little while to get used to, but for me it was two sortes.  Also, the added resolution and fine control of the CH stick was a change from the FF2.  Maybe I had spiking in my FF2 stick, or never set it up properly. 
While my CH Fightersticks (yes, I have two) cost about $98 each they are repairable and I intend to keep them operating. The first stick did not last as long as expected (about 18 months).  Both sticks were bought from Provantage.com.   I hope you can find a stick that you can live with.  While the CH Fighterstick is a good stick, it is not perfect.  I like it.
