I have plaster pool, Diamond Brite or similar. The previous owner of the house left me a combo brush where the nylon bristles are disintegrating and left floating in the pool. I'm about to buy a replacement, but wonder if I should get one that's just stainless steel bristles, or the combo style of stainless steel and nylon.
What are the pros/cons of each? Combo brushes seem to be a few dollars more. Is there some reason why they'd be preferred over stainless steel?
