I am in the early stages of building/designing a 11x14 flat bed. I have some specs from the builders on-line, but in the real world, how long are you guys really stretching out.

I'm a stick and stone landscape guy. Don't think I'd ever want to chase bugs or flowers up close. I don't have any lens yet, but in my 4x5 I have a 90, 150, and a 210, and I feel pretty happy with them, and don't feel the need for more. Most of the time its either the 150 or the 210 so I guess I'm usually pretty close to normal.

So, what do you guys think? Is 3 feet going to be enough.
