The thing going on with clubs is that 1D can have longer clubs. Majors don't (Unless 56)
I don't have the suits in specific order as you can see because the main suit isn't know, however I tried to put two shorter suits in right order.
2C (Bal or clubs, GF) ->
2D = 4+C
2H->2S = H
2NT = Low, LL/longer clubs
2NT->3C= three suited

+++:
All but few wild shapes resolve at 3NT or below. (Except room problem with high shortness club canape )
It is (relatively) very easy to remember
Fits for all three openings pretty nicely (Main exception is 3C as three-suited which is just one shape after majors)
---:
All single-suiters without shortness are lumped in the same. Especially 7th card can make quite a difference. Same goes for 71(32)
There's no min/max -> relay must be practically GF. (Over 1D inv+ with Ds is fine) Of course with min/max you can show only half the shapes in the same room. So it works well only for limited openings, the narrower the range, the better.
I just want some input, what obvious I have missed Experiences of using something along these lines and some with min/max if you have used both would be nice. How narrow opening ranges should be? What after shape is resolved, will ZZ-ask and DCB work as in our 1C relays?
