Reeds are a personal choice, and after spending several months trying out a wide variety of reeds, I've settled on these for the time being. They're consistent and don't require too much adjustment, they produce a nice tone and are very responsive. On my Rico Reserve X0 mouthpiece the 3.5 is about the right strength though I might try some 4's as well. 56 Rue Lepic's aren't right for every player, but they're definately worth trying if you're in search for a new reed.
