Mash height

[BigWilley]

Are there any noticeable differences in the depth of the mash bed when using equal amounts of 6-row, 2-row, wheat or flaked products. My experience has been that wheat will create a slightly shallower mash bed than a 100% barley mash and the addition of corn seems to do the same thing. I have never used 6-row and am curious if there is a noticeable difference. I realize that each particular lot of malt may be slightly different as well as the milling parameters but Im just looking for a general answer.

I'm just speculating (and am by no means an expert at any of this stuff), but it would seem to me that the husk-to-kernel ratio of 6-row vs. 2-row would make for a thicker or (pardon the terminology) 'fluffier' grain bed.
Let those with way more knowledge chime in!
