3" or 3.5" Backplate ?

[EdLancer]

I am going to re-purpose my PC to a mini, but should I go with a 3" or 3.5" backplate as certain pad companies only make their pads for a 3" or 3.5" backplate ? The way I see it the 3" is more versatile as it can take a straight 3" or 4" pad while the 3.5" is only good for a 4" pad.

EdLancer- I`d go 3" and stick with 3" pads. Using 4" pad on the smaller plate never works well for me, just too much unsupported area (IMO, an inch, or even a half, is proportionally significant when you`re talking pads that small). And the smaller pads correct a lot better for me anyhow even if they cover ground more slowly. I`d even think about going 2"!

I’d go with the 3 inch just because of its versatility.

Ok 3" backplate it is, the thing is the 3" Lake Country backplate cost more than the 3.5" Griot`s backplate which sucks. I have some 4" LC pads I use exclusively on my rotary mostly for polishing out overspray when painting and touching up other people`s bumper debacles.
