""Now if you go with a smallish 650, you don't want the annular""

Drag,
That reminds me that Zac told me that when he recommended the 750 over the 650, he said that the 750 with annulars would be just as responsive as the 650. Plus the 750 would give me a little bit of room for any mods in the future.

Now that I thought about it, Zac did not want to sell me the 650 annular when I asked for it.
