For same weight they are stiffer , by definition. Strength /stiffness propotional to depth ???
that is not true "everything else being equal, then an sdm will be stiffer than an rdm" may be true, but same weight could mean wildly different materials and construction techniques.
Im 95kg and use RDM masts on sails cut for RDM masts and am perfectly happy with them. If the sail is cut for the RDM masts there should not really be any issue.
