Spiral Raises playing Precision

[jmc]

I like to raise partners 1M response to my precision 1D opener on 3-cards. After 1D-1M-2M I'd like to use a spiral raise structure of some kind to find out what type of support and raise the 1D bidder has.

Gavin Wolpert's suggestion here for standard players looks good, but all the minor suit information seems less worthwhile playing precision. Does anyone here who plays precision have a good alternative structure to differentiate min/max, 3/4 card raise and possibly other info?
