The stuff I am keen to get hold of but nobody ever stocks is Soric LRC (low resin content) and Soric TF. The LRC would be great for weight critical applications, as personally I think Soric is too heavy for most applications - it does absorb a large amount of resin, especially compared to other infusion cores like 3D PET Core and Corecork. And the TF is the low-print version that is available in black, making it ideal for cosmetic applications behind carbon fibre skins.
