I agree with you, Cab. The only thing that I might have a little different experience with is the initial; the bumpier the cam, the more initial they typically like. All the way to locked out if it doesn't hit the starter too much when cranking. But most of the time, my engines (both BB and Hemi) seem to do well with initial in the mid 20s then with the advance in as soon as possible like you recommend. I use that even on engines with milder cams. The caution comes with load in high gear. You have to watch for detonation when cruising with total in that early. Gearing, weight, converter, etc all come into play with that.

These are my experiences with primarily street driven cars with more cam than stock.
