I have no experience with firdaria, although I do remember reading delineation material from Abu Mashar -

Theoretically, it makes much more sense to put them after the seven traditional planets, because of the Chaldean order, doesn't it? I believe it may part of the reason why the north node is first, because in the Northern Hemisphere, the north was associated with heat and summer.
I cracked open my copy of Abu Mashar, which I haven't looked at carefully until now. wow, it's BRILLIANT! Ben Dykes in his introduction gives complete and clear instructions about how to do solar revolutions (solar returns) with firdaria happily included!
I checked out the delineations that petosiris kindly pointed us to, and it was mind blowing in terms of how accurate it was in defining periods of my life. Used in tandem with solar revolutions and annual profections, and combining that with zodiacal releasing technique, this is a powerful predictive tool indeed.
For those who might be interested, I'll post an excerpt from the Gunzberg book that contrasts the two methods of using the nodes:
Extract from: Gunzburg, Darrelyn. (2004) Life After Grief: An Astrological Guide to Dealing With Loss, Bournemouth: The Wessex Astrologer.
"All ancient written sources say that the Nodes should always be placed at the end of the sequence, whether the chart is diurnal or nocturnal and for all diurnal charts there is no debate that the Nodes fit into this arrangement. All ancient written sources also state that the Nodes come at the end of the sequence for a nocturnal birth and when the Firdaria are set up as a table, this seems logical. In spite of this, Robert Zoller posits that this is in error and goes on to emphasise that if the planets are placed in the circle, then the Nodes rightfully come between Mars and the Sun.
The deciding factor to this argument is whether one works with the circle (Zoller’s method) and recognises the inherent measure and cadence of life or follows the more linear, table-based method of Al-Biruni. Acknowledging Zoller’s work as an empirical medieval astrologer and recognising the nature of the circle as reflecting the days of the week and the inherent cadence and measure of the Moon, then one would be drawn towards Zoller’s method. Indeed, in working with clients, I have had better results using Zoller’s method than the other."
