hackish

Interesting article but I think it misses some of the most important parts about harness/toggle symmetry that cause the spin in the first place.

I sort of feel like the term "prop blast penetration" was made up or mis-typed. Even if you search the term this is the only reference you can find to it. I don't think it's a good term to use anyway since it is confusingly similar to "Prop Blast" and I think the effect of the prop has little to do with exit order.
