walkman, thanks for the advise.
We are ecommerce site, and have about 8,000 products. Each product has over 20 colors. Before Panda, we have a page for each product color, and therefore, we have a lot quite similar pages for each product. Since Panda, we have redesigned our product page to show all colors, and the previous product/color pages are not needed anymore. We had put "NOINDEX" on those pages. But after review the thread, we thought "301" redirect the product/color page to the new product page may be a better option, because it will carry the link juice to the new page.
But, will it cause any troubles?
