BME has always been a great experience for me..
They used to check and x-ray a set for $110.00..
Don't know if that's the case anymore.. Always helpful on the phone for me.
I had over 600 runs on several BME rods. Usually had them re done after 300 runs each time.
I have GRP 5300 series in my B1 (6.535 Chevy) but have few runs on them, so no serious opinion yet.
As far as the MGP stuff, I know they have a weird way of torquing, and if you don't follow their steps I have heard of failures.
BME also has some issues with leaving their rods torqued for long periods of time without use.. I've never personally had a problem, but I know they (BME) don't like it..
