Even at full price it is a hell of a mod. The all white one is really cool. I just can't get over how much it does and I heard the TCR settings for the different SS's are right on. I might have to try a spool. I'm going to order some more Ti from Unkamen and he carries SS430 which is supposed to be one of the best for TC. With these mods you just set one of the config settings up for which ever SS you have so when you put that atty on like for me I have config 1 set up for Ti you set config 2 up for SS430. Then you just change to that and you can change your power settings all you want besides having the 5 faves already set up. Pretty amazing stuff. I'd grab one of those White ML's to put away with my Silver on Silver M's but I'm saving my money for a Q
