One other thing I would add is on a positive note is that I really like the 100% parallel design instead of a drop at heel. It's very comfortable to shoot and stay on target.
One bad thing is they are very heavy in my mind. 40 oz is a lot and 12 oz more than my manners EH-1.
Another good thing is they are fast to deliver with short lead times.
Now with the $530 price I would likely get a manners MCS-T at $445 and add the couple things you want to it or get a much better stock in a manners EH-1 at 28 oz for only $40 more at $569. If iota had their stock for $400 it would be a different story.
