Like most things, the choice is entirely yours. However, I'll give you two things to consider. On the one hand, a pipe unused is a sad pipe. If you enjoy Latakia blends and want to include all of your pipes in your rotation, I say go for it. But remember, once you go down that road there is no turning back. Latikia blends will ghost your pipe and, while you can use them for other non-Latakia blends, you will always have that smoky flavor in whatever you smoke. This is also a good excuse to buy new pipes when the need arises.
Now for the other hand; tastes inevitably change. What you like today may not be what you crave tomorrow. Furthermore, you may find yourself drawn to something unexpected, which may not be an English blend. If you only have Latikia dedicated pipes, you may not experience the full range of flavors. (Although, some pipe men don't mind a lil inter-blend loving.) I REALLY enjoy Virginia blends, but I try to keep every kind of blend in my rotation. Although I love my VAs, sometimes only an English or Aromatic will do. I also struggle with oriental blends, but I always keep one at the ready because I'm determined to understand their appeal.
Like I said at the beginning, it's entirely up to you. My advice is do what feels right.
