5-1-1 vs gritty for acid loving plants

Does anyone have testimonials here growing acid preferring and acid loving plants in these mixes? Azaleas/Rhodies, blueberry, etc?

5-1-1 can be made more acidic by backing off on the lime. Gritty is mostly inorganic and therefore not naturally as acidic so this is not an option. I suppose adding more bark and less Turface could somewhat help but then the drainage and water capacity changes.

I also realize that the irrigation water pH and alkalinity matters more...but for plants placed outdoors in a rainier climate, rainwater will provide at least some portion of watering, making this a bit more challenging.

Thoughts?
