Monte and MrMark -- thanks for the additional information! Those look like really useful items...plus, I'll admit I love using German tools on German cars

I do still have some hesitation about using an impact, since it beats on the sides and corners of the nut more than manual removal. However, these would be good to have on hand for those especially stubborn nuts, or when I'm in a rush.
Elroy -- those Apex products are sweet! Do you (or anyone else) have even approximate pricing on them? I'm just curious.
MrMark -- I can't believe that the Griot's are aluminum and not impact rated...thanks for pointing that out!
