Skinweave is ONLY 12 SP! You can get a T-Shirt that does that! A T-Shirt! Or a bandanna with 10 SP! I'm serious, by the way. 10 SP. On a bandanna.
You can get a Tanaka topcoat with 16 SP - and look GOOD.
You can buy jeans - jeans - with 16 SP.
This is Cyberpunk, not Weeflerunnerpunk - there be mean weapons out there. Skinweave just isn't the be-all and end-all. Not even close.
but the thing that makes skinweave special is that sp12 doesn't count as a layer. so even with the layering rules you can strap on sp16 gear over your sp12 skinweave and achieve effectively sp21 all around. not saying that is bad or wrong, but it does have some major effects on how the game plays out. pistols smaller than 12mm are merely range toys for cubicle dwellers, cut down rifles in duffel bags become standard practice (the only big decision being do you ETE for extra penetration, or up the ROF and get drum mags for hosing down the block), and then people start scouring the rules for broken shit that will bypass SP all together...
come on sard, if you've played this game half as much as you claim you must be hip to the fact that skinweave punches well above what it's SP12 weight would seem to suggest
