I haven't used the flipper, but the old combi is a lot faster on my o.a.p'S bungalows. I can't believe that Wagtail stopped making them. An added bonus for me is that the channel width is exactly the same size as most of the panes. I dogeared mine from the start and have to detail a lot less than when using an applicator and blade.
Having said all that I still find myself detailing when there's no need to, even after all these years.
