I own two Sea & Sea YS-110. I have been very satisfied with them, and never had any problems with them. But after about 10+ years of use, one of the strobes died last year. So I'm looking for buying a new one. The two obvious candidates are the Sea & Sea YS-D2 and the Inon Z330. Since I have been using Sea & Sea's before, that would be my first choice. But then I read about issues about those strobes, and very positive things about the Inon Z330.
Since I still have a functional YS-110 left, I prefer to continue using that (for cost reasons). Are there any downsides with using two completely different strobes? The color temperature are not the same for example.
The Z330 has dome shaped front. Doesn't that make it more suitable for wide angle and less for macro work? I suppose it's also more easy to scratch? How about attaching a snoot? I made a home made fiber optic snoot for my YS-110. While I can still use my YS-110 for snoot work, someday it will die as well. And then I'll probably the same strobe as I'm going to buy now, to have a matching pair again.
