Preach this, grant last is now my favorite last for Alden boots. I’m a 12 E brannock and wear both 12D and 11.5E (the latter is hard to find but maybe a slightly better fit) in both grant and Barrie lasts. My feet are slightly different sizes though (my left could fit 11.5D barrie comfortably but not my right) and I haven’t had that many boots to dial it in.I'm TTS in Grant and -1/2 in TB. Grant is my favorite last for boots. They are sleeker than Barrie and TB, but not as dressy as Plaza or Hampton. Hits that perfect spot for me.
Great last though. I sold my color 8 shell PCT boots in barrie for a pair in grant and love it.
