Hello first time here, want to say hello.
I detail about 2 vehicles per week to add context.

My equipment usually consist of a go to rupes 15 mk3 and a rotary for heavier defect removal.

I was stuck between the Flex XFE cordless vs the Dewalt, but ended with Flex due to faster charge time, weight, and vibration.

After using it now, my biggest concern is the drop in rpms after the battery is about half depleted. Now I understand this is a finisher, so cutting is not the purpose of this. So I want to pair with another cordless.

I am current looking at the XCE cordless, dewalt cordless da, or just skip all together and go to the dewalt or flex cordless rotaries. I find that the flex does xfe does have cutting capability with the right pad and compound, but the run time on max rpm is why I want to get another.

I heard that the dewalt da does have more cutting capability.

What would you guys recommend next, will xce be a noticeable difference or dewalt da, or just go straight to the rotary?

Thanks in advance.
