When we were first looking at the 23WS, I asked about getting the older windows with the Oyster Fiberglass as I thought for sure my wife was going to hate the bonded ones since they only opened a few inches. When I took her to actually see one she threw me a curve.....................she actually liked the bonded.
Now if I told her I was getting the bonded in the beginning then she probably would of hated them.
I am told there is a way you can modify the bonded windows to get them to open farther.
