This is the opener I have been using:
Sharp F1 > Eno + RS > F3P > Ley Lines > F4 > Pot > F4 > F1 > F4 > (F3P )SC F4 > Convert > F4x2.
The difference between this opener and the F4x3 > F1 opener is that it guarantees 6 F4s while also having that nice F3P > SC F4 > Convert if you get a proc vs the non weaved F3P at the end of the other opener.
