... saying some Novus Ordo Masses on occasion? You know, if the local Bishop is there, maybe just once a year like the FSSP, and of course done in the most reverent manner, no Communion in the hand, with Gregorian chant, no handshake of peace, using the first Canon, etc. You're never going to leave the SSPX under any circuмstances, eh?
Realistically, it was the the handshake of peace, communion in the hand, liturgical dances, and so on, that got many people thinking about tradition in the first place. [For those old enough, the constant liturgical changes in the 1960s did a lot too - many people were going to several different churches each Sunday trying to find one that wasn't nuts.]
Near me is a conservative church that does only the NO in latin (and occasional TLM, I've heard). I have never been but I know people who have, and I get the impression that, yes it's the NO, but the rest of the culture around the Mass is there (benediction, no communion in hand, etc.), and people pray. I think most who were searching in the 1960s would have found a church like that home, and I suspect a lot of the younger traditionals too. (At least while it lasted.)
