Replacement Air Filter

[Southpaw]

I'm going to get a new replacement filter for my AFE stage 2 setup.
The one in my truck now is in pretty bad shape.

AFE makes 3 different types of filters for this-

Pro Dry S- is a 7 layer synthetic oil-less filter (99.4% efficent)
Pro Gaurd 7- is a 7 layer cloth/synthetic combo that needs to be oiled (99.5%)
Pro 5R- is a 5 layer cloth/synthetic combo that needs to be oiled (98%)

As long as it is all synthetic it doesn't need to be oiled right? That is wht I always thought. I have not been oiling the one in my truck, because I was told it was all synthetic and didn't need to be.
I guess my question is this - Why go to the trouble of the oiling to gain 0.01% efficiency?
How many of you guys run the dry filters, and how many oil theirs? Any comments or opinions about it either way?

Any insight or help is appreciated.

if it was me i would go for the dry one.......

that's probably what I will do, I just wanted to see if the oiled ones are really better.

right now im running the standard blue one, seems to filter pretty well. Is there any benefit to using the dry one besides not having to oil it??

The blue one is the Pro Gaurd 7.
As far as I can see so far, the only advantage would be not having to oil it??
