I am thinking about wrapping my V&H Big Shots with black thermo wrap. Rolls typically come in 25, 50 & 100ft and I need to know how much is needed.

Have you wrapped your pipes and if so, how many feet did you use per side?

 

Depends how wide the wrap is, but I guessing based on a 2.5" Pipe, and 2" wide wrap you would need the full 100, and then some...depending how you overlapped.
Think of it like this, take you pipe length say four feet, with 2" wide wrap, you would have to wrap the circumfrance of your pipe 6 times for every foot....that works out to 60ft per pipe....this is just roughin it....but give's you an idea....I'm think of doin the same thing
