Excellent point on fir drive Mite. Of the three choices you provide, I'd go the with the small munsterlander. Do you have a size limit? Doesn't sound like it since you're considering the Drahthaar as well. You might want to look at the Large Munsterlander too.

Given how much you hunt, and assuming that doesn't change, I'd stay away from the Drahthaars, Pudelpointers, Kurzhaars.

You might want to look at the Griffon Korthals as well.

Good luck.
