So I was able to try on the stuff with my new suit the other day.
Back protector first impressions:
Pros: This back protector is TOP NOTCH. Really comfortable, great fit, adjustability, and construction, nice and thin but still CE level 2 certified, full tailbone and shoulder blade coverage, the works.
Cons: There are two. One, they sent me the unit with camo trim, when I ordered black. Two, I found it for 100 dollars cheaper somewhere else after the order.
Chest protector first impressions:
Pros: Clever attachment method, looks like it would provide thorough protection, seems to stay in place well.
Cons: Very thick. Makes the suit fit tightly. I would need to ride for a few hours to decide if it would be uncomfortable or not.
Long story short, the back protector is awesome, the chest protector is so-so. I ordered a black race one (got the last one in my size!!!) from the 100-dollar-cheaper place (oncycles.com) and will be returning both the back and chest unit I currently have for now. I am going to try a couple other chest protectors on in person with the suit and back protector to see if they fit better. If not, I will order this one again because the quality is very good.
Here are shots of the suit fit with both on, and the fit of the items under the suit:
