The general consensus around here is that if you're going to use a UV filter, then make sure it's a high-quality one. While I don't have any of them, the Hoya Pro1D filters are a favorite, especially if your budget can't stomach B&W or Heliopan.
HOYA FILTERS - The Difference is Clear
With that being said, since my lens kit has stabilized now, I will eventually upgrade the filters on the 17-70 and 55-300 to Hoya Pro1Ds and then just buy one for the WA zoom when I get it. The only downside is that they don't make them in 49mm; 3 of my lenses are 49mm. For the 2 that don't already have them, I'll be picking up Hoya HMC filters.
If you haven't checked them out yet, you definitely need to check out
