i have 2 of them.not my 1st choice for soft shading.the first one i have is a first generation v2 that actually has its coils in a V shape.it has 6wraps coils with 21gauge wire.godoy changed it later on and made front coil leaning forward and reare one str8 in order to be able to use smaller armbar.also he changed the gauge and made it thinner.dont know the size but i think it must be 23-24 g.the frame is also thinner and lighter.they carry 100uf capacitors so you can understand that these machines are very strong.yes they are all around machines but they dont do shading for realism.i would say oldschool shading.lining with small grouping is great but they cant take more than standard 7L.they are great for color building and packing.and all these in the range of 5-6v.
