this is very hard to answer for several reasons. Most common one, your taste might be different than mine.
I’ve modded mine some time ago, when Novatouches to harvest was pricey, but possible to do/buy.
They’re hard to find nowadays (in Germany), the second sliders i like a lot had been bought from China with some friends, those sliders are not available anymore. We bought a large margin, couple of thousand. They’re a bit longer, which is nice for dampening, i use Hypersphere rings, not loosing much of tactility.
Today there are a lot more options available, that i havn’t tried, maybe some other folks can step in with recommendations that are still available.
Sorry i couldn’t be more helpfull.
