I think the SW comments are probably consistent with what I'm finding.
I too have problems blasting winners with the yonex, but it's great if you want to create short wicked angles to get your opponent moving off the court. The strength for me is at the net and on bh slices.
To give some perspective, I'm mainly playing with a Dunlop 4D 200 Tour. The 200 Tour is a punishing baseliners stick. The yonex is more for a finesse game imo. I'm still playing around with string setups and weight and would like to play with the yonex. I just haven't gotten there yet.
