It's simple with masts. Carbon can be a bit lighter and a lot stiffer than aluminum, but it is more expensive. You decide whether you want to spend more money for a nicer ride.
I've heard conflicting information regarding weight vs stiffness for carbon... I'd love to see actual data
I haven’t got the experience to really tell a floppy mast from a stiff one, but everyone says the stiffer the better.
Given the number of choices on the market now it would be great to have metrics to make comparisons between products and to really know what you are getting. There are some of course, and each manufacturer has their own marketing strategy. Similar to the idea of manufacturers labelling their wings with basic comparable info such as area and wing span. Other KF thread. Maybe not so easy with wings.
Mast info should be easy, no? Dimensions, weight, “modulus of elasticity” and Stiffness (EI) both axes.
Moses say their 101+ masts are “high modulus”. But they use “top materials” for all their products. Axis say their latest mast is stiffer than the previous model. Not saying any of this isn’t true. Latest Slingshot aluminium masts only seem to have changed in appearance and small change in length (full length mast from 35.4” to 35.5”). They don’t tend to talk about the weight of their foil too much.
I’m sure someone has done some kind of home lab stiffness testing of their masts, which would be the only way with composite materials. If anyone has actual data it would be pretty interesting.
