I'm quite happy with my new Vectra L2. It's quieter than the stock return, plus it has more uumpph, and I think I'm at around 8,000 lph with it. It is rated at a max of 11,000lph. I've recently added a 'Y' outlet connector to the return pump, just to split up the flow coming out of it. I think it only cost a fiver or something like that and it has helped reduce the sand being washed away in certain spots.
