There's not much sense in going with an oil K&N with the introduction of high flow/high filtration synthetic dry filters on the market.

Just remember, when you push the envelope on performance, in turn you sacrafice reliability. K&N is a prime example of that.

Which is why I'm still hesitant! I typically don't keep a car for my than 2 years but I'm trying to break that trend with this car, so I may play it safe.

I'm not sure that you're aware of this but paper filters are able to catch more dirt when new versus oiled cotton. However, oiled cotton flows air at much higher cfm. The filter abilities of both are so close that more people prefer the oiled cotton because of the added cfm flow. Paper, though filters more dirt, it also loses it's ability to flow cfm fairly soon when it gets dirty, unlike the oiled cotton ones. So this is a hit on performance.
