I am not sure if you can still get those Sniper Rifles anymore. I keep my LDRs and really enjoy them. I believe I had to dismantle the Longbow because of vault space problem (tough decisions). I like the LDRs better. Good luck with the chase. Note: I recommend you running the VOG and try your luck getting the Praedyth's Revenge. Ascend it w/ Etheric Light. It is a great sniper rifle (6 rounds, firefly, very stable, void damage, good firing rate).
