The 8 does pack a lot of power. I prefer the Becker Pro, V1 Classic and the new Org 7 as I find better control and feel. I had zero comfort issues with the 7 and I strung it up with some very stiff polys while testing. I would pick it leaps and bounds over the 8. With the Sensor handle systems, Volkls tend to always feel very comfortable.
I think the 8 is plenty comfortable, too, but just packs a tad too much punch for me. The 99s is also comfortable as the open string pattern offers a very soft and forgiving feeling stringbed.
