When I was building my 493 I had the opportunity to look at all those brands of rods and a few cranks side by side when I made my decision.
The best looking rods were the K1's so I chose them because the first 4 out of the box were identical. I looked at the cranks and if you didn't label them I couldn't tell the difference
I ended up going with the Eagle because it had been cut 10-10 and the radius was much cleaner than the others after a pro crank shop had cleaned it up.
In all fairness I didn't compare an "out of the box" Eagle crank to the others
I just didn't want to buy a "kit" online so I ended up with an Eagle crank,K1 rods,and Wiseco pistons and it runs solid for almost 7 years now.
