I saw a set at the shop I work at with exactly the same problem.
I think Bluehouse is a rad company offering great prices, but unfortunately I've had a really mixed experience with my 189 Maestros.
My skis have gone from fun, poppy, with some stiffness under foot to dead and super soft. I would compare their flex to a JJ at the beginning of the year (bit stiffer) and now they are much closer to my EP Pros. This happened within 20 days on them and I am really frustrated to be completely honest.
On top of this, I've talked to a number of people around the Central-Northern VT area about their skis and have heard very similar things. i've even heard that people have had their traditionally cambered bluehouses become rockered.
Not sure if it's bamboo or what?
