As Daveyboy said, more of a concern in high revving engines, but I have seen those rods fail in engines where OE rods would likely have been as reliable. The crown design is the obvious one, material quality, machining consistency and how they behave when impacted are other considerations.Sainz rods are good, from the applications I've seen.
Alot of engine builders use these it's true; I can't speak for them, but my experiences and the correlated information from the builders I work with, has taught me the importance of quality in this area. The piston/rod shown above were supplied to me by a customer, he wanted me to fit the head to the bottom end. The pockets could have been machined, perhaps the stress point on the rods could be reduced, but it would still be trying to make good parts that I wasn't happy with the quality of. Thankfully he appreciated why and returned those parts and I ordered my own ones and built it from scratch. That situation is always a dilemma, likewise old parts or different management etc, because I feel for the customer's situation and ramping costs, but I can't take the risks on for them; it's best for everyone that it's just done right from the word go. I'll resist the need to post further anecdotals
