Help with pedigree 9 chocobo abilities

[Holy-chan]

I had a gigantic wall of text written, but, instead of bothering you with my life story about my chocobo, let me sum it up: pedigree 9, 4 stars everywhere except 1 star in acceleration. Winning most of the time but intending on getting the perfect 4 stars chocobo.

My current race abilities are Increased Stamina III and Choco Cure III. I have nigh unlimited stamina. I can hold W the entire race with no fear, and I want to keep it that way. The one and only time I ran out of stamina even after Choco Cure III (excluding end race Meteors) was that one time I was stuck with heavy between two people with Briar Caltrops going at around my speed in a small passageway. I oftentimes am close to running out, but I don't quite. If I do, Choco Cure III is there for me. But, my low acceleration is my biggest problem, and I consider cunning better than acceleration as my 4th go-to stat, seeing as I race on all three tracks.

I was considering switching one of my two abilities to Head Start, to counter the low acceleration. First of all, is this worth it, or are my current two abilities the "safest" path for overall first places? And, *if* I am better off swapping one ability for Head Start, should I go with Head Start + Choco Cure III, or Head Start + Increased Stamina? I am trying to ask people who know these things in enough depth to be able to give a concise answer. As this is a very specific question, I could not find any information in any other topic.

Thanks in advance.
