QQQQ is a better timing for Pivots from a Twinkle, because it puts the man forward on the downbeat, which is generally considered better phrasing-wise. Of course, to do this, you will be exiting with a forward action instead of a backward action, so you have to pick your choices from a different bag. Here are some ideas:
1. Plain old Feather / Forward Continuity
2. Curved Feather / Hairpin - SQQ
3. Rudolf Ronde of any variety (popular)
4. RF Forward, then Rumba Cross
5. Be creative... realease the lady into open position with a free spin or underarm turn of some sort.
If you underturn the last LF pivot, you can also try one of these options:
6. Turning Lock to R.
7. Right-Side Hinge / Corte
8. Release Lady into open position
Anyway, you get the idea. Pretty much any figure that begins with man forward on the right foot works. Or, if you underturn the last step, you can follow with any natural figure which begins with man back on RF.
While I'm at it, I should mention that the Twinkle is not the ideal entrance to pivots. Have you considered an Outside Spin or Tipple Chasse?
Sincerely,
Jonathan
