The problem with aluminum rods for me is that they have a short life span. I can't afford to buy a new set of $1300 rods after 300 passes. At a higher power level of course better parts are required. It's up to each individual as to how much they gamble on a part. That's why I posted here. My experience with the parts I mentioned have been trouble free for the number of passes at the stroke and RPM run in my motor. I've put over 500 runs on the crank. My bet is it had at least 200 on when I received it.
