Sorry for the real late response but I was doing some Ala and Giant Jho. Best time was 1:28 for Gian Jho. Now for that run I wasn't the status gunner. I was the pierce gunner. Here was my set up.I've improved the set but only slightly. Here is the armor pieces. Diablos+ cap, Diablos+ vest, Diablos+ guards, Alloy+ waistlets and Gobul + Leggings. I had a 6 expert with one slot tali. Here were the guns I used. Here is the second one which when both are maxed out this one beats out the other one however it only has one weapon slot the other one has 3. Chaos wing,Devil Grin, and Blizzard Cannon. For the above gun you want to swap out the alloy + waist with Chakra or Helios+. Everything else is the same.
Now for the second gun which is.Thundercrus Rex ,Devils Grin, and thundercrus. For the first gun to be the best it can be without doing Adren +2 you need a 7 expert with one slot tali. These are the skills that would be helpful. Critical eye 3,Pierce shot all and pierce shot boost. I can get critical eye 2 with the Chaos wing setup right now.I'm just one point away for getting Critical eye 3. The Thundercrus Rex gun can get Critical eye 3 without much problems.
I just came up with another pierce set up. This one has Great Luck,Pierce shot boost and Pierce shot all. Very easy to make. Jaggi Mask, Diablos+ vest and arms. Vangus coat and either low rank Uragaan leggings or Alloy + Leggings. If you use a one slotted weapon then you need a 4 fate tali. If you have more slots then you can get away with a lesser fate tali. If you don't have any fate talis then just put in a 10 skill with the tali. In case you guys didn't know the Jaggi Mask affects the amount of Regular Quest rewards. The normal quest reward for Jhozilla is timeworn Charms so you get more then usual after the hunt with Great Luck or Good Luck.
