How would the bidding go if North held ♠Kx/ ♥Axxxx/ ♦xxx/ ♣QTx? You should have a SAB available here if I understand how things work - would it not have been an option?

Good question and analysis without knowing the system well (unless you found it on the internet).

Yes, opener had the option of making an SAB with 3♣ and finding out that responder had 3+♣ and 3 Controls (with a 3♠ response) and now opener has no room to find out there is a perfect fit for 6♣. The sequence 1♣ - 2♥/2♠ responses are used when the major suit is usually KQxxx or better to avoid this problem. Thus, with the hand you propose, ♥Axxxx, responder has the option of treating it as balanced (5332) with a weak major and responding in the Meckwell fashion of 2♦ = 8-10 balanced.
