Honestly, I'd look into a Mavic EX729 rim for your front bro. I'm running a set on my Demo-9 (Huck bike) and I've barely managed to knock them out of true, let alone bend them! No flat spots either, and I frequently run sub-20 PSI in my front tire.

They're the exact same as the old 321, just new & updated (and I think slightly lighter too). They're a dark grey in color, so I dunno if your "bling factor" will be there, but they're strong as crap and they dont have the ugly "flat" sides on em that the Rhino Lites have. They're more rounded, and look CLEAN in my opinion.

I think you can pick up each hoop for somewhere in the neighborhood of $55 USD, and then build your wheel from there.

Spokes should only cost you about $20 depending on what type you pick, and if you want double-butted or single butted to go with it. Make sure to use brass nipples if you can, they're stronger and won't "tear" like aluminum ones are prone to.

Hope that helps, and good luck with your rim. The lefty is strong, it's definitely your wheelset that's lagging..... especially for a "manimal" like you.
