I've tried on both HG/SS and B/W, and I hate how on Black and White it takes so long to find out if you got a shiny. You Soft Reset once every 30 seconds AND have 3 chances of getting a shiny. But in Black and White you can Soft Reset only once a minute
That's why I'm never going to SR on B/W. I'll just MM for a shiny if I really want one. I don't really like any of the stater's shiny sprites for me to SR for one, except for maybe Serperior. At least with HG/SS if you don't get the shiny you want it's still a shiny that you can keep, trade or transfer, and then try again. Just keep SRing and you'll eventually get it. It took 10 days of nearly straight SRing to get my Quilava after my Croconaw, and I was literally jumping with joy when I got it. (I was alone, but I still would have done it regardless.)
In other news, I've somewhat updated my signature. I've changed Rool's and Knuckles' pics, and I've decided to keep Knuckles as Knuckles. It's grown on me too much for me to change it. I've also learned that I can't add a Sudowoodo to my signature because of the limit, and I'm sad. I really need to get a shiny card, but I don't know how to do it.
Well, good luck to everybody and their hunts!
