I've been working with several PB's on the design of my pool. The one that I am most likely going to use is butting heads with me on coping. I am using flagstone and I like the larger seams and asymmetrical pieces. My PB says he won't do the larger joints or asymmetrical pieces because they are more subject to crack/break.
Here is a picture of what I like from another poster on this board. My PB uses symmetrical pieces with tight joints, to me it looks too "prefab". Thoughts please.
