"Well this kind of got off on a wrong start. But thanks anyways."
Nah, just a simple issue of semantics with your OP is all. Nick and Craig were just trying to give constructive criticism because they thought this was a winter list, I think.
If this is a summer list, add a rain poncho and you seem pretty good to go. The 30 degree bag in the summer seems a bit overkill, but not sure where you will be. For example, I am planning on upgrading to a Zpacks sleeping bag 40F/5C degree to use 3 season, but for here in Sweden/Norway. In the spring/fall just swap out wool base layers for the lighter synthetic ones I have my current SUL summer list, which is here if you want to see it: http://www.geargrams.com/list?id=10426
My current bag is only rated 55F/13C, but I sleep in all my clothing if needed if there is a cold sap. Once I upgrade my bag, I can then cut weight on my clothing worn--lighter pants, jacket, etc. in the summer, and in spring/fall add clothing when needed.
So I guess what I am saying is that your SUL list seems like you are trying to push it to a 3 season list when perhaps it should be more of a summer or 1+ season list. So I say save weight and swap out your 30 degree bag for something lighter, or just a nylon or silk liner if it is really warm. To make it a 3 season SUL list, looks like you will have to switch out your pack and/or shelter for lighter stuff (does not have to be Cuben, though that is a good choice, if expensive). Or just mod it a bit and be happy with a 6-7lb UL gear system.
Right now my spring/fall gear list on my profile is around 7lbs and can go lighter based on a few variables, maybe to 6lbs. A 5lb BW and a 6lb BW does not really feel much different, but a 4lb BW vs. a 8lb BW does from my experiences.
Good luck and hope this helps. Next time, just a little more details or more clear language (this is a challenge we all struggle with, myself included, and not always possible to do) helps. :)
