Guild Wars 2

Hi guys!
What should i build on my dagger pistol thief Equipment wise. I already have the trinkets and acessories sorted out but i don’t know what to take my gear. Im using valkyrie stats emblazoned armor and thinking of putting superior runes of the scholar on them but they are extremely expensive. What other alternatives are there to the rune of the scholar? Im thinking of beryl orbs but they seem kinda ‘cheap’.
Thanks guys

Training wheels, after all that is what the build is all about, PvP with training wheels.
