I can offer minimal help on this one...
I fish with Cortland Peach DT on my 3, 4, 5 & 7 weight rods. I know of the Hook & Hackle line because this line is supposed to be either made by Cortland and sold under the name Hook & Hackle OR it is engineered to be VERY similar to the Cortland Peach DT. The hook & hackle line comes in an olive color. Do a google search on cortland dt vs hook & hackle line. You'll get some good reads and you might gain some insight in to the Hook & Hackle line you're interested in.
Never had much luck with SA lines. I do use Rio Gold on my 8 weight...it is the best WF line I've ever used. The main criticism I hear of the Rio line is that it does not hold up well but I have put in over 2 seasons (OCT - MAY) on my Rio Gold for steel in upstate NY and still casts/floats great. I am skeptical of inferior fly fishing products, I'd suggest you be patient and wait for a good deal on the big auction site.
