I have a remotely mounted Airwolf which appears to perform satisfactorily, but has two drawbacks: first, it is mounted to the firewall (with a doubler), but you still flex the firewall a bit when tightening and loosening the filter. Second, due to the geometry of the mount, the hose running to the filter does not empty when the oil is drained. Therefore, two or three tablespoons of oil always spill out after the filter is removed, and this makes for a bit of a mess. Not a huge issue, but certainly a nuisance that makes the task last longer than it should.
