What are your favorite aircraft types (and modifications) for glider towing in high density altitude and/or short runways?

I fly a heavy two-seater and have been towed in hot/high locations (DA around 10k') behind a Pawnee 235, CallAir A9, C188 AgWagon and a C185 SkyWagon. All four did a reasonable job with the C188 being the best. I think the Pawnee and definitely the two Cessnas had a constant speed prop and did actually better than the CallAir, which I was told had the most HP. I have no idea if any one of them had turbo-charged engines. A low wing, constant speed prop and lots of uumph seems to be the winning combination.
