701, I think you are probably right about the advantages of the SE Quad, but it has it drawbacks in the quality of stuff in the kit.
If you have pretty mild winters with very little or no snow, ice, or steady and heavy winds, then maybe; if you are willing to fix some weaknesses like the hardware. One thing for sure, measure each wire when you get it and record the lengths of each. The wire elements are supposed to be pre-stretched at the factory, but some tell me that that is not so. No advice here, just something to think about, because the length of these wires is critical.
The Maco should perform just about as well and I doubt really that you could really tell a difference except maybe in weight. The SE quad feeder design is an amazing feature, that leaves little to be desired if setup properly.
The big problem with the SE is the metal spreaders as they pass thru the boom. They are not fitted well nor are they secured well at the points of contact. The winds on the antenna may cause considerable wear it these areas unless modified somehow, again no advice here either, but one guy I know tiged his elements to the boom and another used some light weight body type filler to secure them better. It is the sharp edges of the tubing that are the problem.
