There are some pretty amazing TO220 mosfet specs but it doesnt sit comfortably with me when you put them alongside a TO247 package - cause they look tough! I have not used any electronic engineering data to back this up, consider this a gut feel or anecdotal assessment! I also like the mounting of TO247 and the surface area for heat transfer and yes the legs are much more substantial - If I have the space I will use TO247 any day. If at first you dont succeed, I suggest you avoid sky diving.... Cheers Mike
