That's interesting. I am running 2 strains at the moment. NLxS1 and White Rhino.

Any clones i take from the Rhino root with damn near 100% success regardless of how much love or abuse i give them. and they root FAST.

The NLxS1 clones i take, following the same loving process as the rhino, only give me at most a 25% success rate. I've had total failures too where i lose all my NLxS1 and have to hit my grow friend up for clones to revive the strain.

My methods are very similar to what you outlined in your last post, using rapid rooters.

Very frustrating.
