The feeling of any grip, straight, dished, locator, etc., will always be a very personal thing. I could lay out a dozen longbows, all with "straight" grips, and they will all feel different. Even with a straight grip you have differences in depth, width, how they index the knuckle of your thumb, how they seat in your palm, etc. etc. Not that you can't adapt to a certain grip it's just that some will fit you better than others. I have medium sized hands but still prefer a wider and deeper straight grip than most. The last longbow I built has a straight grip that I really like and can be consistent with. Others don't care for it.
The same can be said for locator and dished style grips. You can be very consistent with any of the grips mentioned but they have to fit you, and your shooting style.
