after having it, i can't imagine using anything else. it hasn't given me one reason to consider switching. i just replaced the biscuit with the newer B2 i believe it's called, with the black and brown bristles for 17.50, can't beat that for a 'new rest'. it eliminates so many headaches and hassles that you have with other rests, and it's so simple and carefree to use. the wavy vanes after hundreds of shots are an acceptable trade off for the consistent performance and worry free moving and drawing.
