Maybe no reply because the question is so general. Difficult to answer there is too many variables.
For a start, mango lassi is known to gunk up easy (at least in my experience; I've used 3 bottles of it)
2. Gunk is juice dependent. Some juice gunk up more readily than others. In general, sweetener-laden or chocolate-y types are prone to that.
3. Wattage/resistance high watt low res tend to heat up more contributing to possible gunk / dry hits
4. Proper wicking/saturation to avoid dry burn.
5. What is 'less maintenance'? Some hardcore here change cotton and coil every day or every other day. My experience with lassi was every two days if I'm bothered or 3 max.
6. Are you using rba or the occ? Try spaced coil or 'bigger' diameter coil (2.5mm-3mm). Or maybe 2.5mm contact coil. I've also used 3mm spaced ni200 on tc, gunk up as bad too so idk.
