Those turned out great. And having the parts on hand was a really good idea. Hopefully those things get raced hard.
what filler are you using? Did you clean the rod before brazing? It seems to me that since I started using either Gasflux or Cycledesign I haven't had many pinholes at all. The stuff I got from the LWS was horrible for pinholes.
Your post makes me want to get a blasting booth even more though.
