I would make sure you tell them this because single balance point ain't gonna cut it. They also have to make certain the stick weights clear the control arms and brake calipers so they don't just get knocked off. Usually ok if they don't stack them. Steering wheel shimmy is almost always incorrect tire balance.
Definitely - dual plane/dynamic balance is the way to go. I've only been to one shop that argued with me about this and wanted to do static (single plane) balance. Even 30 years ago, I remember dynamic balancing becoming the norm.

On modern cars, anyone who wants to do a static balance I wouldn't want to touch ANYTHING on my car!

Not to mention how lax they are with the static balancer. I just saw my friend's car, they used 2.75 ounce (or 11 of the 1/4 ounce weights) on one wheel. Absolutely ridiculous.

You can use this website to look for shops in your area that have the hunter road force balancer

Even with a RF balance, you need a competent tech. First RF balance I had, they didn't even break the bead and rotate the tire to reduce the forces, they just slapped weights on it. It wasn't until I asked to watch that they actually put the effort into rotating the tires on the wheels.

Crazy...is there a video of what road force balancing entails?
