Which Wu do you have?
Im not yet sure what I feel about untipped ties. I suspect that they should be lighter, more airy and that this will be felt in the drape. I bet someone in the Noodles thread has this tie and can tell you how it drapes.
On the Wu ties, I opted for shantung. Haven't worn them yet but did tie them. The knot easily but the shantung is very dry and stiff so I expect the effect you describe. Tipping might help eliminate that but I think it's more the fabric. Looking at the Panta not sure it will have the same problem but that's a guess, fabric looks softer.
Anyway guessing your instinct is right, the untiping will make it overall more pliable, in good and bad ways
I have the OIlive Melange and the Prince of Wales. Both unlined. These are the first ties I've ever bought that are 6/7 fold unlined at the tip so it's a new world to me. Thanks for the suggestions on the two Drakes ties. I'm gonna hit up some thrift stores to see what I can scrounge up the inexpensive way first.
