I think I liked jump-up when it was just drum & bass. Used to go nuts for tracks like T-10 and still do. I think back then producers weren't trying to make jump-up but just good, current drum & bass. But as drum evolved and jump-up became a sub genre some producers have solely concentrated on creating that jump-up sound which, really, has been done. And with the exception of a few tracks, nothing new has come to the table.
I can understand wanting that harder, aggressive drum but I think you can find it in techy, neuro stuff without recycling that same old sound. The same applies to all drum. I mean I also loved the Hospital liquid era but I think producers would be wasted trying to keep reproducing it now (not naming names. I'm sure you can).
