The biggest diference is that the Samick Masters+Samick Extreme limbs costs about 750? ( +/- ?500), and the SF Riser/SF SHC limbs costs 500? (+/- ?330). I want to know if the price diference reflects the diference of both sets. And i can't try neither one of them, because they dont exist here in Portugal, so i have to go by your opinions. Ah, the bow is to shoot FITA and Indoor 18 meters.
