Stock profile is 30' for most brands, I believe Bauer falls into this. Graf used a 30' profile as well.
Based on your description, you never re-profiled your Grafs. Over the course of multiple years of sharpenings, the blades have rounded out to something more in the player spectrum (9' to 11'), very little blade contact on the ice.
You could round it out to a 26 or 27' if you want something a little bit less than what you currently have on your Bauer.
You could also go with a Goalie SAM, which is an 11' front third. Middle of the blade on these has a 50mm flat spot and back is like a 27' I think.
Would also recommend giving yourself time to adjust. The new holders are like 1/2" taller than the old cowling combos. It doesn't sound like much, but your entire body weight is 1/2" higher so weight shifts on your feet feel more dramatic. I tried skating with that style skate for over a year and couldn't get used to it.
