Guys I have 0.42 sensi 800 dpi
Depend.
High sensi = You need to have a great mousepad to be able to do 'micro' adjusts, so speed is great but you need low friction pad.
Low sensi = It doesn't really matter, some low sensi people prefer speed pads, other control. You do not need to have low friction pad since you do not do tiny micro adjusts with your mouse. Go with Cordura pads if you live places with high humidity.
I tend to prefer speed pads over all.
