Pumping: Amazing results, & fluid retention?

Its been a long time since my last progress report. I was struggling to find time to do PE cause of work. But Lately I have been caring around my pump with me and pumping 2 a day every other day. I have also been supplementing which has really helped with me gains. I was 7 .5 a month ago. Now I am 8 erect and can stretch to 8.5 in length and my girth went from barely 3 inch to 6 after pumping. Now I am working on cementing that. I do how ever have questions about fluid retention. I am using a luv pump, which is not a water based one, and wanted to know if there is a pump besides the bathmat that will give me a more even pump through my whole shaft?
