I like the Bizarre v2, but the Dragonfly was my favorite until now. The give screw on those machines just loosens the needlebar pin and it rattles louder the more you unscrew. That theory works, but it really wasn't 'give' to me, it was more 'detached'. This Specific has a flex like an armature bar on a coil! That flex increases with the counter-clockwise turn, but the give and flex is always there. Closest thing to a coil, without the weight and constant tune ups. Specific & DF will be my daily runners for a long time
