I've been digging for some explanation of (to me) unfamiliar arrow terms the last few days. I've found quite a few helpful articles but this first one does a very nice presentation of the whole.

This isn't a 'have this, buy that SKU number' article, rather more technical explanation with a few charts. Not much for formula, but those can be Googled as needed.
I almost added this one to " Arrow woods/Spine and 1970's arrow charts", as there seemed to be some overlap...

Very interesting. There is a lot of information in the twincoasters guide.
