I wouldn't play with the same ball inside and outside. You'll either trash the ball playing outside, or have a hard, slick ball that really doesn't compare to any good indoor balls out there.
For indoor, I recommend The Rock (Amazon link). In my opinion it plays even better than Wilson Evolution, and it's under $50.
Best and cheap don’t mix. If you’re going for an outdoor ball, don’t buy leather; get something that will last. If you’re going indoor, get The Rock. It’s like 60$ and my favorite ball to play with indoors.
