Default Experience with multiband Loops?

I'm interested in the experiences some of you may have had using full wave
loops in a multiband configurations.

I have two trees about 135 feet apart with pulleys installed so I can haul
antennas to the pulley height, approximately 100 feet.

I like the low noise of a delta loop or square loop, and am considering how
to add coverage on 80, 40, 20, 15 and 10 metres.

I like the delta loop better from a mechanical perspective, since it
simplifies the support ropes.

I can either feed an 80 metre delta loop at the base with ladderline to a
tuner, and then use it on all bands.

Or, I could "nest" the smaller loops for 40, 20, 15 and 10 metres inside the
loop for 80 metres, and use rope from each outside corner to support. By my
calculations, that would put the closest loops, the 15 and 10 metres ones
about 2.65 feet apart. I'd feed each of them with a separate Q section of
1/4 wavelength of RG-59 (since I'm only running 200 watts).

Any comments on the likely performance of each of these alternatives?
