I am considering a purchase of some (Minnis) Fresco cloth for a few summer suits, and am curious if anyone would be willing to provide feedback regarding which weight would be better--the 8-9 oz. or 9-10 oz. More to the point: would the 9-10 oz. Fresco cloth be too heavy for summer heat (and humidity), and are there any disadvantages to the 8-9 oz. cloth? Thanks.
