Anyone run the OCZ triple-channel DDR3 Reapers (1866Mhz 8-8-8) kit?

Does anyone have experience with these OCZ DDR3 Reapers (1866Mhz 8-8-8)

I'm thinking of setting up a new system with an ASUS Rampage II Extreme, i7 920, and the OCZ Reapers. I'm wondering if others have found good results with those. . .

On Newegg I see everyone making a big deal about the Corsair Dominators 1600 (8-8-8).

But I honestly don't understand why they would be better than the OCZ kit. The OCZ kits is $45 cheaper and is rated at 1866 rather than 1600 with the same timings.

Ok, so here's my rational for considering this memory. . I don’t have personal experience yet overclocking an i7 so please tell me if I'm off in my thinking. . . .

I figure that if you can run 3.8GHz for daily use, then I assume you would have the following options. . . .

Option 1: 190MHz x 20 = 3.8GHz
Option 2: 200MHz x 19 = 3.8GHz
Option 3: 212MHz x 18 = 3.8GHz

So when overclocking the RAM, I suppose you would have the following choices for the RAM multiplier.

With option 1 above, it seems you could use either 8x to get 1520MHz or 10x to get 1900MHz. I figure if the RAM is rated at 1866MHz, then running at 1900MHz shouldn’t be a problem. Or is that where the memory controller of the CPU becomes a limiting factor? If so, I figured if I have to run 1520MHz then I could tighten up the timings instead to 5-5-5.

With option 2 above, it seems you would again be limited to 8x to get 1600MHz. Using 10x would give 2000MHz which may be too high for the RAM. Although the two reviews show the OCZ Reapers getting up past 2000MHz with stock timings (8-8-8) and stock voltage (1.65V) or timings loosened to 9-9-9.

With option 3 above, it seems you could only use 8x to get 1696MHz. Using 10x would give 2120MHz which would of course be too high. But if I had to run the RAM at 1696MHz, I would try to tighten the timings from 8-8-8 to 6-6-6. or at least 7-7-7, again according to what was done in the review.

So based on this I figured that having RAM that is stock at 1866Mhz 8-8-8 would be nice because I could open the timings to 9-9-9 for higher speeds or tighten the timings to 7-7-7, 6-6-6, or even 5-5-5 if I have to run stock or slower than stock.

I know all of this is theory, but this is the reason why I thought the OCZ Ram at 1866MHz 8-8-8 would be better than the Corsair at 1600MHz 8-8-8. I figured I would have more flexibility by either overclocking or tightening timings with this RAM.

By the way, my values for what this RAM can potentially do are coming from these reviews:
