Which Moonclip Rack/Holders for ICORE/USPSA?

Finally crossing over from ICORE Classic to Limited 6. Picked up a 625 Performance Center and am in need of a moonclip rack and/or moonclip holders.

From what I can tell, there are a couple common options:

• North Mountain 4/5 Post Rack - $130-$165 - uses tension against the main plate for retention, relies on double stacking for capacity. Posts are straight up/slightly towards shooter. Holds 8/10 moonclips.
  
  
• Speed-e-Rack - $145 - uses magnets to retain the moonclips; usable for 625 and 686 (if I decide to have my cylinder milled for moonclips). Posts face out from shooter. Holds 7 moonclips.
  
  
• Speed Beez Rack - $160 - uses magnets; usable for 625 and 686. Posts are straight up. Holds 8 moonclips.
  
  
• Double Alpha Moon Clip Holders - $26 each - uses magnets, specific to 625, does not allow moonclips to spin freely, and spacing is adjustable. Leaves less room for gut, but is a non-issue for me. Posts are straight up but angles can be adjusted left or right, and spacing is adjustable. Holds as many moonclips as I buy holders for.
  
  
• Moonclip Server - $140 - spring loaded rack and can load from the same exact position every time, but only holds six. Moving parts.

I've talked to the guys I shoot ICORE with and the opinions are all over the place. Most end up settling on a set of Double Alpha Moon Clip Holders, the Moonclip Server, or the Speed Beez Rack. Personally, I'm leaning towards the DA holders on a dedicated belt, or the Speed-E-Rack. I like that the DA holders are molded specifically for the 625 moon clips for consistent orientation.

If I end up upgrading to a Limited/Open gun, it will likely be a 929, and will need a different rack anyway.

So revo competitors, which Rack do you like and why?
