For me, more than 2 is too much. I sold all my older keyboards and equipment and reduced it into 2 only. Now I'm just using Roland A-70 with controller VE-RD1 and a Triton LE (can't afford to buy the real Triton but I got a good deal with LE. I am going to a module route to utilize the capabilities of A-70. What's the best module out there?
