I personally own all mesh from 200 up thru 500 and I dont use anything but the 500 anymore. It just rocks.
Thanks for your input... it's easier to take the word of someone I'm more familiar with than those that have just recently started posting ( low post count ) or just started posting in an area I visit such as the GV forum area. I'll check what my current supplier has and on my next order, I'll add in a bit of the finer mesh if they carry it.
