Well, these are odd.
They sound a lot thicker in the mids and low mids than the Diadarrios, they have less chime in the highs, they're more saturated - I've had to drop my gain a bit -, they grip a pick more, the set I got is actually a bit slacker than the diadarios that I've been using, but not much (good guess Mr string man) and is in fact tighter sounding.
They have done what I wanted - put high end back in without losing low end (they have more, but its probably just from the extra energy from being slacker but hitting them as hard)
The plain strings are fatter and thicker too. I'm getting more definition in the middle notes in sweeps, where previously it was quite hard to get them to sound evenly with the legatos/picking flourishes on the first and last strings (as is my sweeping idiom), and the sound on all strings is much smoother (comparing to 2 week old but nearly unplayed diadarios on my dean).
Overall they did what I wanted to, but there were a lot of tonal surprises with them. They sound very different to any previous string I've used. Closest comparison is DR Tite fits, but they didnt have the depth in the low end or the smoothness and clarity in the highs. First impressions are very good indeed.
I'll be upping the guages very slightly with my next order and getting more :)
