Maybe it should be clothing based.

How many articles of clothing do you own made from Lycra, Spandex,
Gore-Tex, Neoprene, Polypropylene.

In fact, if you include the correct fabrics, you could take this index
way beyond sports.....

My boss (a confirmed motorhead) brought up Cylinder Index the other day
- how many internal combustion cylinders you own, counting lawn mowers,
ATVs, cars, boats, etc.
While I definitely yield to him (104 vs. 9), it did get me thinking
about an equivalent in silent, people powered sports. I'd propose maybe
a carbon index - how many sticks of carbon you own, including bike
frames, ski poles, paddles, maybe even golf clubs. Any thoughts?
Memorable counts?
