How many of you tighten connecting rod bolts with a stretch gauge v.s. how many by torque wrench?

Don't confuse what people "get away with" and the correct way to do a job...
I to have built 25/30 engines before i started using the stretch method and "got away" with it.....but others are not as lucky .The problem is that they have problems but something else gets the blame for the failure....
This is all in respect to aftermarket bolts.....
Check the new bolts for length..... I have found that you need to cycle the bolts once, then record the relaxed length... keep it for when you freshen up the engine.... Any bolt that grows .0010" or more needs junked. I have found that the new bolts grow a bit, maybe .0005" or so during the first cycle, then take a set to that length....
