1- I'm missing Hawkmoon, Gjallarhorn and Monte Carlo. Various armour bits too, but I'm more focused on the guns. 2- How does one choose between Hawkmoon and Gjallarhorn ? HawkHorn. I need a HawkHorn. 3- my favourite exotic in terms of sheer coolness, is The Last Word. 4- Biggest achievment? Umm. The Vex I suppose. That or any of the bounty exotics. There's still an RNG element to getting a Vex, but there's also a specific task you have to complete before being granted a dice roll, so that's technically an achievment as opposed to a random occurence. 5- Of the weapons I have, I'd say Icebreaker is without a doubt the most universally useful.
