I started a series of workings with the angels of the sigillum. Here's some info for people who'd like to do the same. So far I'd say the angels of the sigillum are in feel, very helpful, kind and patient.
The planetary correspondences of the angels are from the vision where the angels appeared to Dee carrying a sphere of metal attributed to their planet. The angels appeared in the order of gold, silver, copper, tin, iron, mercury and lead. (Sun, Moon, Venus, Jupiter, Mars, Mercury, Saturn).
The following tables are taken from Colin D. Campbells book Magic Seal of Dr. John Dee, but in the traditional order of the days for convenience. I highly recommend getting this book if you're planning working with the ee's of the Sigillum.

Oration (my version in enochian):
Conjuration of Madimi
(Move and appear, powerful spirit of God of Justice, [MADIMI])
Zacad ca od Zamran, micalzo gah a Iadbaltoh, [MADIMI]
(In this name of God [Aaoth] and the secret name [ILAOIVN])
a-oi dooaip MAD [Aaoth] od laiad dooaip [ILAOIVN],
(out of whom creation continually descends and raises)
geta casarma Qaa pild uniglag od farzm.
(In this name Daughter of Daughters of Light move and appear)
A-oi dooaip Pasbs-a-Pasbs (Noromi a Noromi for Sons of Sons) de olpirt Zacad ca od Zamran:
(and be friendly unto me for I am the servant of the same your God, a true worshipper of the Highest).
zorge, lap zirdo noco MAD, Hoath Iaida.
Campbells version in english based on the Heptameron:
I hereby conjure the most powerful, holy & potent angel of God [Child of Light],
through and by the most sacred name of God, creator of all that is upon the earth,
the seas, and the heavens, [God Name]. By this mighty name, I further command and
move thee from thy Order of [Angelic Order] by virtue of the mighty Archangel [Archangel],
who dwelleth in the celestial abode of [Planet], to appear unto me here in this place to answer
unto my desires to the Glory of His ineffable Name. Amen.
Both versions work by my experience very well. Madimi actually turned up before I had the chance to start anything at all, after I had everything set up and were waiting for the correct hour.
As for ritual equipment, all I've used has been the large wax sigillum.
