Another alternative, that we've been using for a while and like a lot, is to play transfers after 1
♦-1M. So 1NT shows both minors (either can be longer - with 6 diamonds and 4 clubs, 1
♦-1M-2
♣-2
♦-3
♣ is stronger than 1
♦-1M-1NT-2
♣-2
♦). 1NT is intended as forcing but doesn't contain any game forcing hands opposite a minimum response, so responder can pass once in a while (haven't yet

). 1
♦-1
♠-2
♦ shows 4 hearts, 5 diamonds and not enough to reverse, a very awkward hand otherwise. The transfer to 2M shows 3 card support, a raise shows 4 card support (of course one could use these for good and bad raises, but we've found knowing the trump length is more useful).
I'm not sure I understand the rationale behind this transfer. As far as I know there are two main reasons for transfers:
(1) It can right-side a contract. This is the less-important reason. That doesn't seem to be a big win here, since opener's 1NT bid with both minors is fairly likely to wrong-side the notrump contract. With two suits already bid, the most likely suit contracts have already been "sided" anyway.
(2) It allows the transferrer another call, which can help to describe his or her hand more efficiently. However, in this auction responder has a wide range of values. Presumably over 1
♦-1M-1NT, responder's 2
♣ is non-forcing (otherwise you can't ever get out in 2
♣ when responder is weak, which seems bad). Similarly over 1
♦-1M-2
♣, responder's 2
♦ is non-forcing. So if responder actually has a good hand, he or she can't accept the transfer and you haven't really gained anything. The potential benefit is that when responder is weak and
does accept the transfer, opener gets another call. That's potentially great when opener has some "big hand" and instead of being forced to jump to the three level to describe, opener can start with a transfer and then plan to make another call to complete the description! But in a precision context, these "big hands" don't really exist.... opener is already limited to something like 11-15 high, and this means he or she's not going anywhere if responder wants out of the auction unless holding extreme distribution. But all your jumps and reverses are available for those 6-5 hands and 7+card diamond suits.... Anyways, I can see how transfers would be a big win when opener is virtually unlimited but not so much in a precision system.
In contrast, using the free 1NT call to show the
highest available rebid (instead of shifting everything down one step) creates space for a 2
♣ call as an efficient game force. For example, compare 1
♦-1
♠-1NT (hearts) to 1
♦-1
♠-2
♦ (hearts). In the first auction, opener can force game via a 2
♣ (4th suit) call with plenty of space to spare, or can sign off in diamonds, hearts, or spades. In the second auction, presumably responder can pass (although potentially this is awkward since 2
♦ has a wide range) or bid 2
♥ or 2
♠ or 2NT as non-forcing. In order to force, responder has to go all the way to the three-level.
