Ive tried an e-blade, and an angel, i like the e-blade, but i cant afford it, nor the amount of paint i'd shoot of with it, so im sticking with my Blade Evo Cocker. heheh (and im with cockersrule)
IR3 good feel fast enough, accurate enough and reliable. Mine have never let me down. Of course I might get around to a Viking one day so don't rule them out.
