The LX Airhog is the closest thing to a TM in every facet on 2 cords available for sale today. A 1.5" wand is only a limiting factor in certain set ups, but not all. Honestly, I don't see diminishing returns in these examples.If you spend $1200 to gain 5%, well we get the point. And there’s a certain point your simply done. Booster or not, your always going to have a 1.5” wand limiting anything down the line. Get them to exchange that 1.5” wand for a 2” and be done.
