Default Pooling multiplexed libraries after ligation, before PCR

Does anyone do this with the TruSeq kits? Illumina advertised this feature very strongly in their presentations in my area, as a huge time saving feature of the TruSeq kits as compared to the older sample prep kits... yet the product manual doesn't say anything about it. I'm a bit worried about uneven amplification of the libraries during a pooled PCR. Any comments?

Would that also cause jumping errors and waste of sequencing reads?

Hi I'd like to refresh this thread. Has anyone had success with TruSeq library prep, if you pool your adapter ligated samples prior to the PCR enrichment step?

Pooling prior to PCR amplification is not recommended. It precludes the option of adjusting the concentrations of individual libraries to obtain equal read depth.

Done once. DO NOT attempt it. Some libraries just dissapeared.

We didn't do that. In theory, it may cause unbalanced library pool. Some libraries could have very low sequencing reads.
