Hey guys,
What kind of firmness/color has worked for you? Hard to tell what to spend the money on. Links appreciated.

Depends on what you're using it for. Rehab or general strength training. I used the blue and green a bunch for rehab but started with the orange/red because I was weak.

Both but mostly rehab. Had several finger injuries this year and I'm trying to build up my tendons and ligaments over the winter.
