iff you had to pick between a 3 element trap tribander or a 2 element monoband beam, what one would you go for?

That all would depend on what band's your going to work. The monobander wont compromise for other band's other than what it is resonant for...Clint VK2ACM

Weeelllll- The monobander tends to a contesters or serious DXers "weapon of choice." The tribander is more of a general purpose antenna. So the answer depends on what you want to do.

If I intended to have a single antenna for general hamming the tribander would be my choice. As high as I could get my wallet to stretch, of course.  

If I intended to try for the top of the DX honor roll, a set of dedicated towers with stacked monobanders would be just the ticket.

Personally, if you have any interest in 12 and 17 meters, I would go for a Tennadyne Log periodic - five bands.

This depends on your interests.  Most tr-banders are for 10,15, and 20 meters.  With sunspot activity at bottom, are you interested in 10 and 15 meters?
With a monobander, what band are you planning to operate?  I assume you are talking 20 meters.
15 Should start opening regularly in a few years, do you want to wait that long?

The loss of bands with the monobander is far more noticeable than the comparative loss of performance with the tribander.  If you are only talking about having one directional antenna, unless you intend to only operate one band anyway, the tribander is the best choice.  

That is doubly true since "even a temporary solution that works will become permanent", and you likely won't change antennas for a few years.  In that case the monobander would leave you missing the great propagation to come on 15m and 10m in just a few years.  Actually, there is great propagation there now, just for less of the day than near the solar peak.

Have you considered the "StepperIR"? Looks like the best of both worlds. A mono bander on any band within its range.

I have had many different ones over the years, and my best is a 3 element Steppir. I currently have that one up on the roof tower.  I also have a MA5B up and use it for a spotting antenna.  It is about 4 sunits down from the steppir.  I say spemd the money, and get a 3 ele steppir for 6 - 20 m and put it up at least 30 feet high, and higher is better,
