As a direct comparison I unfortunately have no idea. I actually looked into the Greddy ones and was originally going to do a group buy on them. However after reading about all the dodgy ebay ones I started to question how good the Greddy ones were.
After reading so much about the Dimple brand and how they were ment to be the best available on the market, I figured it would be the better option
Haha don't feel bad man, it filled so bloody quickly.
I have your name noted for the next one though if you don't mind waiting till than.
