That's a great write up. If I didn't have so much home building going on. I would be posting up . Things at least somewhat useful. Alas I have to read, dream and think. I was wondering how 4166 works in the 458. Has anyone tried it yet. No signs of H335 on the shelves yet . Nor H4895 or AA2460. But I do have some 2230. So all is not lost.
