I brewed a very similar kit, basically their Chinook IPA kit with some Citra at the end. That beer is absolutely fantastic, one of my best among 13 brews so far. I'm sure this particular Breakwater kit would turn out pretty good but you may want to add a little gravity or dry hop depending on if you want more ABV or hop aroma, respectively. Adding gravity is easy. Adding hops, well you can add Citra or Chinook and it would be good. 0.5 oz is a little low for a dry hop, but I like hops so that is just me. I did 1.5oz of Citra dry hop in the beer I explained above.
t-royboy, as far as gravity, I'm not sure how you would have got such a low OG compared to the kit saying 1.049. There really is no "efficiency" to consider in extract brewing, either you put the extract in or you didn't. From there the only real variable that affects your OG is how much water that sugar goes into. I pretty much stopped measuring OG on any of my brews because I found I'm always within 0.002 of the expected OG.
This kit for example calls out 3.15 lbs LME and 3 lbs DME. 3.15 pounds LME @ 36 pts/lb is 113 points. 3 pounds DME at 43 pts/lb is 129 points. If you put all the extract in, then you put in 242 points of sugar. If you put that sugar into 5 gallons then that gives you 242/5=48.4, or 1.048 OG.
