In retrospect, cold type paved the way for the vast range of modern digital fonts, with the lighter weight of equipment allowing far larger families than had been possible with metal type. However, modern designers have noted that compromises of cold type, such as altered designs, made the transition to digital when a better path might have been to return to the traditions of metal type. Adrian Frutiger, who in his early career redesigned many fonts for phototype, noted that "the fonts redrew don’t have any historical worth...to think of the sort of aberrations I had to produce in order to see a good result on Lumitype! V and W needed huge crotches in order to stay open. I nearly had to introduce serifs in order to prevent rounded-off corners – instead of a sans-serif the drafts were a bunch of misshapen sausages!"
