This rubber was an experiment due to my love of DHS tackies on my fh, and because XX uses a similar rubber for rpb. I'd learned rpb with focus 3 snipe, a completely non tacky rubber. Even boosted, this rubber is no where near as fast, but has a higher throw and much much greater spin. Just like tackies on my fh, you have many many gears and can easily create varying arcs and spins. The control and feeling is incredible and even at 37 degrees, boosted this rubber feels perfect for bh. The slower speed will allow me to develop strokes and blocking, moving me away from the TPB. Highly recommended. Cheap price too!
