Tony,
I could not agree more with you about the importance of the wet test.
I have questions for your tall sons. Do they find the neck message jets effective, or are the jets hitting them somewhere well below their necks? Do they find that when sitting in the lounger that their feet are being messaged, or do they have to move their feet to fit in the envelop of space?
At 6 feet tall I find that the neck message is somewhat below my neck, but if I squinch (is there such a word?) down to allow my neck to be pummeled, my feet are too close to the foot jet and I must angle them to the right and away from the jet to fit. I can't imagine how a taller person could find a different outcome in an Envoy. I am hoping your sons can help me here.
Thanks,
Bill
