Recently I've found out about SIT Silencers and found them to be very much to my liking. So, I figured I'd give some of their other strings a shot and ordered several, including a set of Power Flats. I finally got around to putting them on one of my basses - a Warmoth Jazz loaded with DiMarzio J's. Yesterday I had a gig and they had their first road test. Wow!! I love them! I was using an Aguilar GS212 with and old GK800RB and it really sounded great. They sounded big, smooth and fat but were still very clear in the mix, lots of authority. I usually use Chromes, but sometimes I find them a little too agressive for a flat. Great on some basses, not so much on others. I've tried DR's (eh), and LaBella's which aren't bad but they're pretty pricey. TI's are great strings but I cannot play them - way too soft for my touch, like playing rubber bands. I'm very happy with these SIT's and at $16 a set they won't break the bank. I recommend you give them a try.
