First off, congrats, its an awesome gun. I was lucky, it took me exactly 25 strikes. Mine is on my Warlock. I think you have a decent roll, Third eye comes in a lot more handy than people will admit, I use it myself over the speed reload perks because I just use gauntlets that increase reload speed. I would roll for Braced Frame because it maxes stability without reducing range like hand laid stock does, and Hidden Hand I believe is superior to Headseeker for this simple reason: This gun is a two shot headshot whether you have Headseeker or not, so why not use a perk that helps you land those headshots? This gun is a lot of fun to use. I outsnipe snipers all the time from distance with it and use it on almost every map. Good luck.
