I would venture to say that if he could hit the 7-8 kilodollar range for that level of performance, he'd sell more than 4 times as many arms.
I love the price/sales equations that factor in on items.
At 5K, I bet he'd rule the waves completely!
I could easily see this arm in the Tri Planar, Graham, Kuzma, Schroeder range and doing gangbusters.
Either way, I wish him success....and hope for some trickle down that actually works!
