When Klingbeil existed, a Klingbeil factory rep told me fixing the length of the blade by the length of the outsole only made sense on full custom boots - because the length of the outsole could be set to be the same as the length of the foot (perhaps the radially projected length of the foot? - which might depend on factors like heel height, and other things). In other words, perhaps you want the front and back of the blade to match the front and back of your foot in some way. For example, if the toes don't touch or come close to the front of your boot, maybe full length is for most people too long.
But I think the ideal length of blade, and the exact mounting position, is to some extent a matter of personal anatomy and personal taste.
It is also possible the optimal blade, length, and position depends on what type of skating you are doing. E.g., ice dance uses the toe pick less than freestyle. And it certainly might depend on your individual flexibility.
Ordering two pairs of blades of different sizes gives you more options. But of course it increased your costs.
With all-leather boots, if you heat mold and punch, one would heat mold first, because heat molding mostly undoes punching. But I'm not sure if that is true if you have a thermoplastic stiffening layer. Maybe it even depends on the specific thermoplastic.
In particular, I don't know if there are any boots with shape-memory-polymers, that return to their original shape when heated. That might be a wonderful thing in some ways, because it would give you the opportunity to reshape the boot as it wears and breaks in, and it would be great for buying used boots - but such plastics are probably more expensive, or might be inferior in other ways. tstop4me, are there any boots with such plastics?
