Ken,

I am not so sure I agree with the statement that it is vulnerable to collapse from wind loads etc. Actually far from it! In the Sobon guide he does have examples of various forms of lap joinery being held down by a single peg vertically.....no M&T. The gunstock post according to some of his writings was very much a thing of UK structures and seems to have died out a bit in NA.

But yes the potential uplift of the tie beam is easily solved.
