I've had a 2-stack of TH7s up for about 4 years (40 and 76 ft). I've
never seen a time when the lower is better. Generally, the stack is
best, upper second, lower third. I've heard this "folklore" about the
lower one being better, but have never seen it. Is it that the sunspots
aren't back yet, my location (EPA, abt 70 miles from ocean), or
something else?
