Just reviewed my ships and it seems that my Python and my Asp are both A-rated. My Cutter could use some more love but when the A-rated module costs 160M+, I think I can take a break on grinding credits for now.

I'll be looking at working on my FSD first, I need three 5A FSDs (Asp, Python, DBE) and one 7A FSD. Reading the linked blog now.
