Mae hwn yn gwestiwn a glywir yn aml yn ein cwmni mewn perthynas \u00e2 mewnosodiadau a chaewyr edafedd gwrywaidd, a'n barn ni yw bod gan edafedd bras lawer o fanteision a buddion dros edafedd m\u00e2n.<\/p>\n<h2><strong><b>Trywyddau Bras<\/b><\/strong><\/h2>\n<p>Mae edafedd bras yn fwy gwydn ac mae ganddynt fwy o wrthwynebiad i stripio a chroes-edafu.
