Based on what i've read around here, it sounded like the RDS was the key issue when picking a mosfet, that and one big enough to handle the current. which was the criteria I used when looking for mosfets. Its like LED drivers, there are an overwhelming amount of options, and precious little information about why one would be good or bad for something.
So, what factors do you need to know to pick the right mosfet?
RDS, VGS? ??? ???
Are there any good websites that might help learn, and or pick out a good part? How about one for LED drivers, that sure would be nice!
