We play T-walsh where transfer completion shows a min bal. hand (without 4-card support) or an unbal. hand with clubs and 3-card support; 1NT shows 17-19 bal. Any suggestions on how to handle a double of the transfer bid (preferably independently of whether the double shows just the transfer suit, or is T/O of the suit implied)?

Options seems to include:
a) XX: 3crd support (support redouble); 1M: 11-13 min bal. with a stopper in the transfer suit and only 2crd support; pass: 11-13 min bal. without a stop; 1NT: 17-19 bal and too bad if no stop.
b) 1M: as without the double, but promises a stop; pass: as 1M, but without a stop; 1NT: 17-19 bal. with a stop; XX: 17-19 bal. without a stop.
c) 1M: min 3crd support; pass: min without 3crd support; 1NT: 17-19 bal. with a stop; XX: 17-19 bal. without a stop.
and likely a few other permutations.

Thoughts?

We play xx as support but I think you could play xx as support with an unbalanced hand and accept with support and balanced. Then pass is often bal with doubleton support.

This may wrongside some contracts when x is lead directing but you can't really avoid that unless you never accept.

We pass with a balanced minimum without support and complete the transfer with a balanced minimum with 3-card support.

We swap one no trump and redouble, an idea we saw Lauria-Versace playing. So 1NT shows unbalanced 3-card support and redouble shows the strong balanced hand.

Thanks for the input.
