I had rapidwinders on both of my Ms (M6, M4-P) and think they are the best accessory you can get for your M. They add little weight but provide great functionality and last forever.
Don (DAG) has done wonderful work for me at a reasonable price. Tom A stands behind everything he make better than anyone else.
Never had a 4, but it felt natural on my M4-P.
