have a set of Relex 2 sails and from 6.2 to 8.6 they need 3 masts 430,460 and 490
I have the 430 and 490 in Enigmas . Was wondering if there is much of a difference in the earlier RedLine masts in
regards to bend characteristics etc . obviously i need a 460 so looking at the possibility of the Redline 460
cheers

I would recommend you the latest 90% SDM from Severne (I thi it is called blue line).
You get the latest curve and a great quality product with the option to upgrade your sails when required.

but the redline will work.
i have rigged reflexes on these masts
