Well I pulled the trigger, twice. Ordered a clear/blue el cheapo spinner cap on ebay for $13 including shipping and then ordered a lovely yellow-fumed Bororegon 3-hole flat-top cap for $49 plus $5 shipping. When I step back and reflect, I can't believe how much money I'm spending on carb caps and pearls. The good news: I've developed a strategy to reduce my Catholic/Jewish(parents and neuroses!) guilt: When I seriously indulge myself, I always try to make a donation to a charity catering to the poor and/or disadvantaged. So I got two carb caps, 10 pearls in multiple sizes, and the local Salvation Army got a $25 e donation. Can't wait to see the little ruby pearls spinning around my Rio's bangers without me having to work up a sweat hand spinning the quite nice cap that comes with it.
