I’ve never thrown the hour, but it is a huge size difference from your dv888. So if you want to throw something different it could be a good way to go. Lots of people seem to like it.
I really like my di-base, it has a nice solid feel to it without being too heavy. I can push it pretty fast without it becoming unstable (I’m not a very fast player, though). It’s also not hard to catch on the string since it is nice and wide for it’s diameter.
I didn’t like the bearing that came with it, though. It was noisy and kind of low on spin time. It probably just needs cleaning, but I got fed up and just threw a twisted trifecta in there and I’m loving it now. It was a little tough to get the bearing out: thirty minutes in the freezer followed by a couple of minutes of wiggling it with some pliers. With the new bearing it has nice spin times during tricks and combos.
The di-base is a only a bit larger than your dv888 in both diameter and width. If you’re looking for something not too much different in size to the dv888 I think the di-base is a good choice.
If you don’t mind a used yoyo, the bst thread is a great place to look as well. As long as you find someone with good feedback you shouldn’t have to worry about the transaction being “risky” and you can get some very nice deals on good yoyos.
