The shorter blade wasn't a transition, even on back threes. The transition has been the higher heel, which forced me more on my toes. This causes more scratchiness.
FWIIW, if you lengthen the heel on any GIVEN boot, and you don't shim to compensate the resulting tilt in the blade, that places the toe pick further from the ice, assuming your leg and foot orientation stay the same.
So, Neverdull44, you could have tried shimming the bottom of your heel, to make it longer, and lift the toepick off the ice. In other words, somewhat consistent with what others have said, it wasn't the higher apparent heel height that changed the way you skate. It was the relation between the forwards tilt of the foot and the tilt of the blade.
Unfortunately for those of us like
me (but maybe not you) who hate high heels, and would like to have our feet level, if you sand off the bottom of your heel, that places the toe pick closer to the ice. You can then shim to compensate - but that effectively gives you high heels again. Yuk!
I wonder if there would be any disadvantage to a boot designed for a flat level footbed, without the tilt or bend at the ball, assuming the heel and forward mounting area were positioned to get the blade inclination right...
