I have a nice set of HE/S 5s (EMG 40 Size). They're super versatile and clear. They're 4-wire so I can switch each to series/single coil/parallel. I had my bass set like that for a while, but honestly just like the single coil mode, so they're hard wired that way. - I moved them from one bass to another that didn't have room for switches and I didn't want to drill.
So, to answer your question, yes, I do find Delano pickups to be "worth it". Having said that, one thing you might try is raising your pickups. Decrease the distance between the top of the pickup and the bottom of the string.
There are no rules about this exactly
start here:
Bass Side - Treble Side
8/64" (3.6 mm) 6/64" (2.4 mm)
go here if you can get away with it:
Bass Side - Treble Side
7/64" (2.8 mm) 5/64" (2 mm)
If your strings start to magnet onto your pickups, you'll have to increase this distance until they don't...
Changing your pickup height can make as much difference as a fresh set of bass strings. Before you spend Delano Dollars, try raising your pickups. You may have just the pickups you want already, but don't know it...
