I can't say this will be the case for others but here is my experience lately with the Jacks.
About a month ago I e-mailed the Jacks about a 900FP +1oz UQ that I wanted as a matched set for my 900FP Sierra Sniveller. I was told that a shippment was expected in June to pay attention to their e-mails for updates. This past friday (5-4-13) I got the email and placed my order on payday (5-7), the quilt arrives today (5-9).
Now that is fast! A custom stuffed UQ to my door in 2 business days, holy cow!
Color me impressed. I'm now the proud owner of a matched set of 20º quilts that weight in at 42oz in stuff sacks.
