No leaks here/nothing noticeable out of the breather bolts, had them installed for a few thousand km, and ride the **** out of the bike. Cleanest looking option in my opinion.

Not at all? Reason why I didnt go this route was because some did get some residual spray, though not terrible
Twin Cams, especially the 103's, from the factory, vary wildly on how much oil they spit out of the breathers. Some do very little and the filter in the Outlaw Breather Bolts stops all, or most of it. Others can spit so much that the Outlaw Breather Bolts cannot handle it and it ends up dribbling or spraying.
All of our intakes accept an array of External Breather Systems (EBS). Even the worst spitter can be handled by any of our other EBS that are options when ordering any of the DK Intakes. You can see them HERE.
I personally own 2 Twin Cam 103's. One of them has spit a lot of oil from day one, brand new, and I run a Premium Discrete Breather System on it with the Outlaw 587 Air Cleaner.
The other 103 is also running an Outlaw 587 Air Cleaner, but on it I run the Outlaw Breather Bolts, and it never dribbles or sprays.
My Twin can spits badly. Using a home made brether with catch can, so I can testify the spitting lol. Do want a cleaner look tho and am working on something.
Hardest part for me is right up at the mounting plate.
Got my filter from Fuel Moto and all I can do is hook up hoses rsther than fit it with a nicer looking hose

Cool catch can! A buddy of mine had a new 103 that sprayed badly out the breather bolts for the first 5000 miles. I put new umbrella valves in when we blacked out his Rocker boxes and it does not spray at all now.
Umbrella valve in the head breather assembly on top of the Rocker arm support plate. Even though his was a new bike it sprayed and puked badly. This stopped completely after I installed new umbrella valves.

Yeah, that works sometimes, but sometimes it is not the umbrella valves.
Oil level and oil viscosity are the first things to check, then the umbrella valves, after that, it's probably a crank that is too far out of round, causing the oil pump not to scavenge as well. This results in higher crankcase pressure.
Just one of the side effects of HD loosening up their acceptable mfg. tolerances.
