I am a bevel-up fan in that I use both and favor neither on general principles . Like Jim, I do find that for any tricky figure I swap my Jack's iron for a 50 degree or use another plane. I read where a few folks have left their LA Jack behind after buying other planes. I have other planes but the Veritas LA Jack is still a go-to for me. This may be due to my having three irons early on and just getting used to the expected result from each. Don't blame the BU or the plane itself; for such work I prefer a plane with a chip breaker.
