You can mess with the trigger more if you want. I didn't take the time to really fine tune it as my tastes would be different than yours but it's easy enough to change up if you want.
On the leak.
RTR Offers or did have shims that can be put behind the puncture pin. I saw you were using Lelands, they are great and I use them, they are very consistant in size but are a little shorter than some other brands. I'm guessing when it was reanno'd it took off just enough to cause your leak.
