Funny enough the shoulder on the Rubinacci is by far the most extended. To the point where people who generally don't notice these things will comment on it.But maybe you mean something else by 'tight at the shoulder point.'
I have a tough time imagining how that would work but I guess you might just be more handy with an iron (and copious amounts of starch) than I am.The collar points have to be fairly long and the collar band quite high for the no-collar stay look to work. You usually only get that with bespoke.
More than that, open patch should have some shape whereas flapped patch should be fairly straight.I think if you get flapped patch and then decide to de-flap you'll be left with pretty lame looking pockets.Though I guess you could just save some material and get totally new pockets. Given the nap on corduroy I don't think that alterations will really show.
