Yes.
To my knowledge, the 1/4-inch come in 2-, 3-, and 4-wrap, and the 7/16-inch SLE come in 3- and 4-wrap. 2-wrap are labeled "Professional Only", 3-wrap labeled "Ultralight", and 4-wrap "Revolution Equipped". EXP sticks are 3-wrap and might not be labeled at all. I think there are 5-wrap "Stiff" sticks out there, but they don't seem to be commonly used with 1.5s from what I can tell.
Now that I have 2-, 3-, and 4-wrap sticks, I haven't used my 3-wrap SLE sticks in about a year now. I, like many others here, prefer the more flexible 1/4-inch sticks.
