Im debating between the MVD Predator Zeso Open LE 120cm and the regular Roller version 100cm for Mediterranean/Atlantic reef hunting. Clear water, mostly shore diving up to 20m. Anyone with experience on MVD? Especially interested in real-world range/power differences since most reviews are only about the inverted roller.
Also open to other speargun recommendations in a similar price range.
