Crawler Tire Insert Comparison

I remixed this just a bit, after I put it up I realized I forgot a few things that I wanted to put out there.
Passing on my few years experience with different tire inserts. From home printed two super expensive. Pros and cons of each and what I see has the best value for your dollar while trying to be completely unbiased. 
Full disclosure, I am a team, driver for SL3D.RC, but that did come well after discovering and using these inserts for quite a while. They are by far the best value for the dollar and neck and neck with the highest performance inserts. I’ve tried, and I would highly recommend you give them a try too .
