Just something useful to know and that I found at Kerkythea forum these days:

Differences between MLT and MLT(BPT) Wrote:

• MLT (Metropolis light transport) should only be used with mesh light emitters or HDRI (which will render caustics) but not with KT point (onmi) or spot lights if you want to get caustics;
• MLT+BPT (Metropolis light transport with Bidirectional Path tracing) can handle all kind of lights including KT point and spot lights and in all situations giving caustics;

* MLT is a bit faster then MLT&BiPT
