Ive been talking to my cousin in the Philippines and he said he can get me some mods. The ones that he said he could get was the grinder mod and the tvs mod. I did a couple of research and actually liked the bio mech and nzonic. Is the the grinder and tvs mod worth it. I could get the bio mech for the price of the two combined. Also since he will be sending me a package, what else would you guys recomend for me to buy. i already have a provari and a vamo with the RSST and Igo-l.
