Disagree, a filter will offer minimal resistance to the air, thats what its designed for, its called a breather filter for that reason. Its just to stop the tube sucking up crap if theres a slight vacuum. If you look at the standard tube, theres a valve on it which requires a little bit of preasure from the crank for it to open(at least the same as a filter), mine clogged after a while which probably resulted in the split of the tube and since it was disconnected, I haven't misfired either.
100% vent to the air with a filter. Some people even connect it to the exhaust but i dont think its necesarry.
Every one to there own just I that filter does get blocked then where's the crankcase pressure going to go so for my own peice at mind I'd always have a catch tank venting to air with just a filter is the cheeper way of doing it.
I know alot of people do just use a vent filter but that's not the way I'd do it works the same with a catch tank but with the catch tank no vapours will leve into the engine bay and it has low risk of getting blocked only prob is requires draining but safer in genural
