Welp, the reviews turned out to be pretty right on, and so far I'm loving them! Even with the heavier gauges, the tension is very low for flats so they feel like a lighter gauge (not quite as loose as TI Jazz Flats but way looser than LaBella Deep Talkin' Flats or D'addario Chromes), and I'm not having to adjust the string height or neck vs. the Dunlop Super Bright Nickel rounds I've been using on it, which is a huge relief! (EDIT: might have to adjust the D string down a little, but we'll see tomorrow once the bass settles in) All I had to do was reset the intonation and I'm in business. They are also the smoothest feeling flats I've ever used, bar none, and unlike most other brands of flats I've tried, there's no initial stickiness.
Of course, a full review of flats is impossible when they're new since the true test is when they go dead, but initial impression of the tone is full and solid with increased midrange response, which should serve me well when they go dead, as the mids are always the first thing to go, and that's always bugged me with flats. Only had a half hour with them, but so far I'm quite impressed. If you're into flats, I think they're definitely worth a shot!
