If your joy is 160 then go with the array that will maximize the results.  Multiband arrays are going to be compromise and degrade your 160 performance.  You need to determine what is more important.  You still might be able to use a 160 array on the other bands but not optimally.

I am pondering an eight circle array.  At present my only ham band that I am QRV on is 160 meters. A few years ago I had 28 thru 24 GHz all percolating, but the maintenance was killing me. i was a slave to the station. Now I am having fun! Rather than tweaking with noise figure meters and VNAs, I now do all my work with wrenches and chainsaw.

There are several choices for 8 circle arrays.  My question is how much benefit would I get from the single band version as opposed to a dual or three band choice?  Reading the hype is always fraught with danger.  Practical experience is always better.  My thinking is that if there is a distinct advantage, I would go with a 160 only setup and forego the other bands.  I can carve out a 200 ft circle with a little chainsaw action. I have about 180 ft of field available now, so can get the room with not too much trouble.

I also better hook up my 160 transceiver quick. It is still packed away from Field Day!!
