We actually tested all the Monti 140/2 from several bunches and they all felt "better, softer" than mine.
I agree that they feel different. However, I've never felt a 140/2 feel so rough than the white blue pinstripe I got (http://luxire.com/products/white-blue-pinstripe)
Lab test is an option if I find a lab closer to home than the usual one in India.
Thanks for your answer
Just wanted to point out I've often felt Thomas Mason fabrics in person in the fabric book and then had a shirt made from them. The shirt usually doesn't feel the same way once it is made until after quite a while.
Just an observation. I have a feeling that Monti also offers a huge range of 140s. Luxire's may well be on the low end for that price.
