sounds as if you are getting it where it should be. you said you have the final and driver at 4.1 volts. is that the voltage at the gate to each. if so you may pop one after awhile. best to keep them at 3.5 to 3.8 volts . if too high they will run hot and fail sooner than normal. you can try it if that is where you have it at and if one blows you will know what could be the problem.

just to throw a wrinkle in you mods, you could even try a couple 13n10 mosfets which will give you a little more output. I have been able to get 40 to 50 and some times more out of a single 13n10 in a cobra 29. do not use the 13n10L mosfets because they only take about 1.8 volts at the gate and pop real easy. I have only done 2 so far with the 13n10 mosfets on the 29's.
