I'm curious, because my qh foams quite a bit (not nearly dripping but you can really tell she does when I get off her and look at her mouth). Which means (and in fact feels when I ride her) that she's relaxed and accepting the bit (BTW, it took her long time before she started moving correctly and relaxed, and that's when foaming came in too). However my paint foams just very little (she does, you can tell too, but not nearly as much). She does feel relaxed though.
