Well I have been experimenting quite a bit on the Moire Wraps discribed by Scott Throop and Bill Colby some months back.  Here are some nuances I have played with. 

Burnishing threads is MEGA important.

Lots of finish between layers really enhances the movement.

Two thread Moires(that is two in the under and one over with one sacrificial) seem  to be better for metallics because metallics in 3 thread moires seem to overpower the other threads.

Three thread Moires (that is 3 threads under and on over with two sacrificials) seem to produce more abherant patterns.  I like using 4 different colors with the darkest on the over wrap.  If you do a three thread with only one sacrificial in the over then I often just bet a stripey pattern more like one gets using varigated thread.

Some interesting experiments I have done lately with fun results are:

Moires with both layers being open.  I have done them with stickers underneith or just contrasting colors on the blank.   The more thread I have used the more open the look and the more abherant the patterns.  Just completed a 4 thread 3 layer job with the bottom layer of 4 threads,  3 coats of finish, some stickers from Jim Ellis at Bill Mar, next an open layer with one Dark Green thread and 3 sacrificials, 3 more coats of finish, then another open layer.  Each layer goes in a different direction.   I really liked the results.  Will post pics when I get the final finish on it. 

I think the two open layer combination might just produce some really unique looks if done over Crosswraps, weaves or even marbling. 

Of course with all this finish and thread it is not something you want to put on a walleye rod or something you want to keep lite and sensitive. 

I will update if I come up with any more brainstorms.
