Useful chart, once understood. (There was a post on the other thread that helped me figure out that "warm" and "cold" simply showed the range of temperatures for a given amount of insulation.) By the way, PL Silver has a CLO/oz of 0.72. I submit that even the 10% difference between PL Gold and Apex might be difficult to feel, so above 40° F, take your choice based on other factors.
Careful with that chart, it's a little dangerous...
I am still tinkering with it and getting more feedback from folks here and at BPL.
I have since added a "COLD" column. Some people bottom out more than originally realized.
Point being- Personal experience with APEX should set the lower or comfort temp. I say 40, some say 50, some say 60- depends on how you sleep and how you build/use it, and a little mystery too.
CS APEX is the safest choice considering all the variables out there. One layer of 2.5 is a good starter project. At worst- you will have a nice, light summer quilt that you can play with and determine your own rating with. If you like the ease of construction and don't mind a gram weenie level of weight difference- Make another one with 5oz of APEX.
PL is great on paper, great in clothing- what is not known is if all the quilting devalues the lab rating a bit. WV makes very interesting and innovative things with it, but his design goes a long way to cover any quilting loss- and as he says- you may not even notice the difference when it's all said and done.
Keep in mind- that chart is for a gram weenie (me) pushing things a bit. I don't mind if I make a project that doesn't work- if you're only making one- stick with APEX.
Thanks for this advice, Bill. I've been researching this and trying decide which way to go. It seems to me CS APEX should be my choice.Originally Posted by Just Bill
