I am finally ready to add transfers over one club openings. However, the options feel overwhelming. Any recommendations or links to prior ideas, appreciated.
The basic framework is: 2/1, 5 card majors, strong NT, one club=2+ (clubs or balanced), one diamond=5+ and unbalanced.
Thank you in advance.

Here are some relatively simple and well documented suggestions. I think these are not best, but they improve on 'standard' in simple and obvious ways with limited downside. It's therefore comparatively easy to switch over.

• T-Walsh - there was discussion on style in both this thread (despite it explicitly mentioning not using T-Walsh) and your previous unbalanced diamond thread. I've also seen Michael Goetze's T-Walsh be linked frequently, though I think it's not the best starting point.
  
• Unbalanced diamond, transfer rebids after 1♦-1M is straightforward. In the previous threads I mentioned my own preference, which differs from these transfer rebids.

I play 2 very different versions of TW

The first version uses 1♣ - 1♠ as GI/GF with opener then shaping out. 2M are always promised unless long Clubs. This approach established strength early.

I also play a version which plays transfers/relays up the line, with strength usually determined later. It also uses 1C-1S & 1C-1D-1H-1S to show certain types of hand.

I have tested a number of approaches given this is the most frequent bid. I do have a preference for a 3+ unbalanced ♦ given this almost guarantees 2M in the 1♣ opening and reduces overloading in that bid.

Happy to share notes on these.
