Winslow? What garbage. Just kidding. I have one for my alto. I dread the day that thing runs out of the little rubber rings. I should buy a surplus... As far as it goes for ligs, you don't necessarily need to go crazy. You'll definitely notice results, but don't break yourself financially trying to find "the perfect ligature". It's like the mouthpiece argument. I have $2000 worth of mouthpieces (though two of them are a Jody DV, and a Sugal), and I could've gotten by with just a legit alto and tenor piece, and a jazz alto and tenor piece. I personally right now am digging just a plain 2 screw selmer lig for my Jody. Beats what I got out of the Rovner, and it's not over the top or anything.

im sure the guy making winslows will sell you more rubber-ring-thingeys true, dont break the bank on ligatures. the money is much more well spent on a mouthpiece. the lig just refines that sound.
