I've never hit with the Volkl so I can't compare, but I did recently buy a couple of M Speed 98's. I think the spin potential is really good. It feels very flexible on ground strokes. I found the head to be too light for me so I've added some lead tape. After I added the weight to my liking, I find that it has the power I need. It is still rather low powered compared to many racquets including my previous fischer and prostaff classic 6.1's. The sweet spot is rather small, but when you do hit it, it is a great hit. Good on volleys and serves for me as well. I think this is a really different racquet worth trying out. It doesn't feel cumbersome even with the lead tape. Great control as well.
