I have a 155 bowfront. I love it. There is a little distortion if you press your nose up to the glass (as I'm known to do) and look sideways.
There is an odd effect where everything is slightly magnified. You wouldn't notice except corals placed in the middle of the tank look like they are quite a bit closer to the front. As a result, placing a coral directly under a bulb can't be done by looking through the front. You would need to look from the top. No big deal, just kinda odd.
I highly recommend the built in overflows.
If you wake up breathing CONGRATULATIONS!!! You get another chance to do it right.
