Yup, spend a bit more time on guide foot prep. That is important in my book. Also maybe a bit less thread tension.

As you said, the bigger thread is easier, esp when getting older. Lately I use the A on the under wraps and go over with C or D.

Sometimes in your case after grinding down the guide foot I wood get some red finger nail polish and coat the guide where the thread is going. So if you do get a gap it is less noticeable when some other rod building guy is giving the rod the stink eye.
