I love the Slow Hand, I have tried it on each character and by far prefer it in the hands of Sal. I have also tried other Hyperion weapons with him but for me the Slow Hand works the best.
This is the build I use now.
Slot 1 contains my Fire SH for fleshy enemies.
Sot 2 is where my Slag SH lives. I like to fire it every few secconds to keep the enemy painted purple while I lay waste with either my slot 1 or 3 SH depending on the target.
Slot 3 holds my Corosive SH for Loaders/Armored enemies
Slot 4 I always reserve for a FFYL weapon so fill it with whatever you prefer.
The LH is great not only for the always helpful ammo regen but also for the boost to Insite
No real need for an explenation here so moving on.
Chain Lightning/Lightning Bolt.
For stripping Shields and because they regenerate their own ammo.
Hyperion Allegiance +39% Hyperion Damage/+40% Hyperion Reload Speed.
Fom what I learned reading some of the other posts on here, the Allegiance Relics don’t affect the weapon in your left hand, this is ok since weapon slots 1 and 3 are your main hand slots and contain your main source of damage and Sals offhand holds his slagging tool.
I find jumping and shooting at the feet of your target with first Slag then either Corrosive or Fire, depending on the target, works best and with Insite boosted to 10/5 your movment speed is greatly increased when you take damage.
This setup isn’t realy good against Raid and some main story Bosses but shines at what it is intended for, Mobbing and supporting your team with the 4.1 Team Ammo Regen.
If you have the nessary gear i suggest giving it a try and i hope you enjoy it as much as I do. Sadly I don’t have the abillity to make a gameplay video but if someone out there does and has fun with this set up I hope to see some footage of the carnage.

Thanks @Chuck80 for the advice.
I decided to keep Asbestos because I don’t really need the healing and it seemed more useful since the SH can cause DOT on the user at close range.
