Favorite Sprayer for IPM / Foliar feeding Plants in a Trellis?

As the title states, just looking for input on what others have found to be the best sprayers for treating plants that are in a trellis net.
Pump sprayers, Atomizers, etc..
What's you favorite piece of equipment and what products are you running through it without issues?

Anything with a mist nozzle on it that really breaks apart the water molecules into fine mist when sprayed... seems the smaller the water molecules the better, i wouldnt use an atomizer as im sure there will be a lot of residual build up on the disk that will eventually have you replacing the disk or entire unit depending on the unit (a diy mist maker could work because you could service the mechanical parts yourself... i usually by extra nozzles because my compost tea (no matter how filtered) seems to clog up the nozzles after some time and they need to be replaced. So i try to buy a 1 or 2.5 gallon sprayer with an adjustable nozzle.

Chapin 1949 build a soil has one I think. You can thank me later
