Held a wobble board against a straight edge today, never going back

We had a 4,000 square foot driveway in Fresno and my crew was using the old magnesium floats like we always have. But the surface kept showing low spots no matter how much we worked it, so I pulled out a 10 foot straight edge and checked it right after the bull float pass. That's when I saw how much the board was flexing in the middle, so I grabbed a wobble board from the truck and ran it back over the whole section. The difference was night and day, the slab laid down flat with way less effort and the bull float marks disappeared almost completely. We finished the pour about 45 minutes faster than I figured and the client walked it this morning saying it felt like glass. I still use a mag for small pads and garage floors, but for anything over 1,500 square feet I'm sold on the wobble now. Has anyone else made that switch or do you stick with the traditional floats for big pours?
