The crower maxi-light K24 rod is very light ~430g. I got my first set almost 3 years ago, but it came with 5/16" rod bolts rated @ 220,000psi. There's a 280,000psi uprated rod bolt option that Brian recently informed me of.
I like Cunningham rods a lot - they're the only rod that I know comprised of a 2 piece forging. The Rod and cap have different grain structures for maximum strength which resists oblongation. We have a couple sets of the regulars (non-ultralight) and those are about 580g in a 6.250" rod. They come with 3/8" rod bolts rated at 280,000psi.
Carillo makes an excellent rod, we've run them in the road race engines without any problems whatsoever. They have 3/8" rod bolts and I'm unsure of their rating. Most likely 280,000psi.
I have Pauters coming in standard K24 length and won't know the particulars until they're done.
Never used Eagle rods.
