Sometimes its not what is said its how its said.
The gentleman who told me this information had no stake in doing so. He has modded many skimmers and told me that the pumps wont last as long, he did side by sides with mesh vs pinwheel. The only reason I spoke up was to let the original poster know about this. I didn't think it would get side tracked into what you believe or don't.
If you go to RC you will find that the some of the biggest supporters of mesh modding have since gone back to pinwheels after using them for 6-12 months.
I have to rely on what others tell me. If they are not trying to sell me something or don't stand to gain anything it holds more weight with me over someone who has an agenda.
But you all need to read my tag line again, because its true.
