>>10849113They do have metal on the "Blade" part - DranzerSpiral is actually blue and silver paint on the areas where it's metal. TT just purposely underweighted it.
DranzerSpiral is best for Attack, but when it's 8 grams below the normal range for an Attack Blade (27 vs 35 grams) there's no point. They also made DranzerSpiral weirdly unbalanced as well, picrelated.
At least when the plastic remakes in Burst were first coming out, those were on par and decent.
