There are a lot of choices of shafts with a 4B2M MPF. I think if you know the weight of the shaft you are looking for, the choices can be narrowed down slightly. The link below takes you to an article about choosing the right shaft, and if you scroll to the bottom there are links to spread sheets with all the Wood, Iron, Hybrid, and Wedge shafts we currently carry. My suggestion would be to download the Wood Xcel spreadsheet and then you can look at all the 4B2M shafts in the same place. You can sort the spreadsheet by weight, price, whatever. This will not have the shafts you mentioned, but will show all the newer products.
