The Rovner LGX, to me, is a hybrid ligature. It's fabric-based, it has a metal cradle that touches the reed—but not a stiff one like the Versa series, and it has the heft of two massive metal bars that hold it to the back of the mouthpiece. On the inside, it has 28 metal "fingers" that adapt to the shape of the bark on your cane reed (or the plastic on your plastic reed — hey, I don't judge), yet are flexible/springy enough to have a little "give" to them. The result is a ligature that has a lot of headroom for volume, because the cradle can vibrate with the reed when played at very loud dynamics. That's my theory at least, and I'm sticking to it.
This is my personal favorite of the Rovner ligatures I carry, but it's a little more expensive than the rest. If you want something a little cheaper, my second-fave is the Versa-X
