How much better is Spa flex over something like Braided nylon from BulkReefSupply? I'm guessing that Spa is easier since it can be glued directly to the solid pvc? I've finally getting to my 46g bow build and I need something to attach to the 1.5" and 1" TRU ball values and I don't want to use rigid pvc due to concerns of cracking the tank. My floor has a lot of play in it.
Go with a 1 1/2" coupling on your spa flex to a 1 1/2" to 1" reducer on the other side of the coupling. Connect the ball valve with normal 1" pvc pipe. This way you'll have the shortest run of hard pipe it's gonne be covered by the coupling and ball valve anyway
