The problem people are often not interested is because carry comfort is highly subjective, and most people people generally find the rated weights to be HIGHLY optimistic.
I've never met a "UL" style framed pack that carried 30lb comfortably. Tolerably? Yes certainly, but maybe my idea of comfort and yours are different.
The most weight capable frame I've met in that style is GG's gorilla, unfortunately, it's a massively uncomfortable pack due to the rest of it's design, so it's null. (The reason the frame is good is because it's a single piece U shape, pre-bent higher modulus Al alloy)
The ULA Ohm style frame is good for up to 20ish lbs, I seriously doubt any other carbon fiber straight shaft on the sides design is going to do better.
Now the Goat Pack will actually carry real weight comfortably, but it weighs 40+ ounces. Reason? It has a real frame.
I think it's about time we stop referring to a couple of random material stays as "frames", because they're not. Especially when they're made from carbon fiber arrow shafts or 1/8th inch hardware store scrap aluminum. I'm sorry, but a stuff sack with stays, is not a framed pack.
That's my rant, having not seen your pack William, I'm not commenting on it directly. So I hope you don't take offense.
