Idle Set Screw Tool

I’m tired of messing with trying to get a small 1/4” wrench in that tight space to adjust the idle. I’ve googled and found several flexible ones but they all use various "bits". I’m looking for a dedicated 1/4” hex on a flexible driver shaft. I don’t want to have to keep up with more bits. Like this but no bits. https://www.summitracing.com/parts/lil-55250

What are you guys using?

 

A little Gear Wrench.

 

Would something like this work. It's a 1/4 on the end.
