You've only discovered what all loyal Trangia users have known all along.
I love my Trangias, and you get used to shifting the windshields to maximise heat.
I converted to Trangias after watching a friend cook bacon and eggs one morning. Pancakes are a cinch, too.
The BEST part about Trangias is that the heat is much more usable for cooking than the intense heat of other fuel stoves. This "slowness" irritates the heck out of instant-solution people, but they usually end up with burnt food on the bottom of their pans, so they make no real gains. And the Trangias don't clog up and need maintenance.
But hey, can we keep this a secret? We don't want everyone knowing.
