Great work with this thread Eli.
I think it looks fine without the talon, how you have it in your first pic. I don't think base compression is really too much of an issue for most backpackers with a frame like this. There will be a tiny bit (the strap angle is reminiscent of the larger One Planet (Australian) packs like the McMillan) and the upper straps will do most of the rest. Its not hard to let your sleeping bag loft out to make up the rest.
Haul loops: A common waste of time IMHO. Its not hard to get used to putting a pack on without them, and generally its a bad idea to actually haul using just that loop anyway. If you were hauling more than 20lbs with this pack (ie roping it up a small cliff face or scramble) you run your haul rope through the shoulder straps and around some of the others up top. I've heard of haul loops on even very respectably made packs (with top quality 12oz ripstop canvas fabric…) failing under 40-60lbs. The only way around that is to build them very strong and bomber, but that adds weight.
