Triangle will work fine.

160m probably not; it's a bit short. It would help if you included a
relay opposite the feedpoint to open it on 160m.

Anyone have experience with horizontal loops in a triangle shape?

I have trees on my property that will allow this configuration. I'll
have about 100' on each of the three sides. It is pretty much an
equilaterl triangle, and the height should be about 60 feet. I'd like
opinions before I go to the effort of getting it up. I'd also like
opinions on whether or not it should tune at all on 160M. I have an MFJ
balanced tuner to feed the 600 ohm ladder line I plan on using.
