Compared to the sheer amount of 'feedback' on the MID + MP, the HD really seems to be lost in the shadow of its popular relatives. OR IS IT? I use + realyy like the HD but the Mid + MP obviously way outsell the HD. Any HD supporters out there? Compared to the MP I find the HD is more solid-feeling, a bit stiffer feeling (stringbed), has a bit more SW, has more 'plow thru' and is generally more stable. Less spin, but still more than the vast majority of non-HD racquets out there....and I hit flat (eastern). Thoughts/comments?
