770 Diesel oil-bath or dry-type air cleaner?

I've got a 1550 with a 770 diesel engine, considering changing the oil-bath air cleaner for dry-type. Two questions; anybody have an opinion which is better? And, should I look for a 1550 dry-type used or is there something new I can buy?
 
Want me to start something here that has no basis in scientific fact? lol
I've mentioned this before and been told I was nuts. Maybe so,all I have is anecdotal evidence.
I've got a 1550 with dry element,a 1600 and 77 with oil bath and had a Deere loader tractor with dry element. When I was running the four of them every day in the winter feeding cattle,I always had a bigger problem with condensation it the oil of the ones with the oil bath filters. No idea why. It's just the way it was.
 
Now you do know that the 1550 was available with an oil bath air cleaner or a dry type air cleaner. Also the hole in the hood is in a different location. Me I would use the aircleaner that matches the hood. Also the 770 aircleaner is smaller than a 1550 air cleaner. The only Oliver that had a dry filter replacement for an oil bath aircleaner was the 1800A series diesel. However the very late 1900 C series diesels went to dry aircleaners right before the 1950 was introduced. Just like Lund my 2 cents worth. How many hours a year do you get on the tractor?
 
I am restoring the tractor with "occasional use" in mind, perhaps 40 hours per year. It looks like the previous owner beat the hood with a rock to make a hole for the 770 air cleaner stack. It's not pretty. And the hole for the original 1550 air cleaner stack is still there. So either way I have a hole to fill. Parts book for the 1550 shows 160624AS for the air cleaner assy. I guess I'm on the dry-type simply because all my other (running) machines are dry-type. Perhaps I'm wasting my money and time.
 
Maybe something to do with ambient temps. Night time, air cleaner drops to several degrees below zero, but moist air from the feed/cattle?

The argument from Landrover, when changing from oil to paper filtration was that paper was more efficient and that oil baths were not suitable for turbo operation. Now whether that was oil mist, or fine dust, erosion of the turbo, I am not sure.
