To be honest, I was looking at running aluminum connecting rods in my engine, and was eagerly looking at these. The enfield all have alloy rods stock, and the new ones are cast (

) except for the interceptor, so I'm running out of options.
For the CB though, I know the carillos exist, but at the price point they run at, it seems a tad much for an average joe build. At the same time, the cyclex rods and ape rods are a great option, but I imagine a beefy aluminum rod can be used to great effect on a street bike (such as the RC goldenrods, etc...). I know two race guys who're running the ebay MC supply rods and have sucess, so I figure something that has good replaceable ARP fasteners, and with a nice polish would have a much higher fatigue strength. The reduced weight would also be awesome for a stock crank. And yes, I'm all for starting the 'should I run alloy rods in my bike' debate!
On the other hand, 4340 H-beams/A-beams with PB bushes at near that price point is also pretty sweet.
