Would some variant of “snauk(t)” or “snaught” work for you? Your brain might be expecting ablaut in the style of “teach” / “taught” or “catch” / “caught” rather than that of “sing” / “sung”.

How do you feel about “(p)reached”? “Snaked”?

A fun fact about “caught” is that it’s a relative neologism. It uh, caught on after people decided they didn’t like “catched” for whatever reason. (I guess it has something to do with tangibility / concreteness. Most other -atch words are used for objects.)
