There is a very slight depression between the front and rear foot straps. It's so slight, it would difficult to measure, but light can be seen through it. It is between the back of the front foot straps and the middle of the rear foot straps. The first picture is a SB W49 and the second is an SB W44 (this picture came out upside down). Both boards have quite V from the front foot strap all the way the rear. They both also have a lot tail kick on the last 6 inches or so.

is this slowing me down, or is it just a tiny imperfection?
