My Current wand is a 1.5 and a 12" head.Something tells me there is a limit to how much a wand can impact results and efficiency.
I too believe it is a great wand but also believe the step up will yield results that might not be in proportion to the investment.
But I am also learning everyday and my opinion should be taken with a grain of salt.
I would go to a 2" with a 14" head. You may be right
That's a pretty penny for that wand for sure!
