No spoilers necessary. I did say please avoid comment if you dislike the agreements of this pair, but I concede it is tempting to discuss them

Nevertheless, my objective as stated is to obtain votes of I/A who can immediate themselves in the named agreements.
You may be able to guess why.
But that said, and while we are OT:

At the risk of being too sour about this sort of thing, I really think these types of questions should be solved by the bidding system. You're going to hold a balanced hand opposite partner's hand very often, and the notrump ladder should resolve bidding issues you may have with balanced hands. Even in an up-the-line approach, using 1♣-2♦ and the slower 1♣-1♦; 1X-2♦ helps resolve these problems.
I agree about the inferiority of up-the-line here, but saying that is heresy here in Italy.
I still play it because I have no partner willing to take that plunge.
I also play XYZ, which smoothes many edges, just like 14-16.
I'm not sure what you mean by "using 1
♣-2
♦": as a weak jump (traditional here, but not that useful IMO) or as something else?
Playing XYZ we can always stop in diamonds by bidding 1
♣-1
♦; 1X-2
♣;2
♦-P; we need your slower sequence as a game force.
