Samidare doesn't grab me immediately like Watashi ga iu.. did, but I still like it quite a lot. I'm also a huge fan of the dancing style they have been giving, they do a lot of position changes and dancing almost in a round, instead of mostly staying in the same location while they all dance the same choreography, it's really refreshing to see.
Sayuki and Tomoko also totally owned the PV for me, both look gorgeous (whoever style their hair did a fantastic job), and I was really surprised, because until the dance break I felt as if Karin was in the background and not popping at all, comparatively.
Man, I'm just paranoidly hoping that everthing goes well for them until they properly debut, because right now I am just so satisfied with them as a group, they are easily my second favourite after Morning Musume. I also hope that their success lights a fire under S/Mileage in a similar way that C-ute has done to Berryz. This way, H!P can go rule the world
