Where do you position your drogue? Closer to the fin can, or closer to the payload section?
A little background on my thoughts for asking this question:
1) I flew my first dual deploy rocket a little over a year ago and have just 5 dual deploy flights under my belt.
2) For those flights I positioned my drogue closer to the payload section containing the main chute. Reasoning - with the payload higher than the booster under drogue, you don't have to worry about the main getting fouled by the booster as it deploys.
3) A couple days ago I was searching TRF postings to help with a parachute purchase decision and read a thread that got me thinking. The way I understood that thread was that some position their drogue closer to the fin can. Reasoning - at apogee separation, the drogue slows the fin can first as the payload section continues on its path a little longer. This decreases the risk of the fin can catching up to and colliding with the payload section. However, I would be concerned that this puts you at more risk of the fin can fouling the main deployment in that it is above the payload section under drogue.
