I can't really chime in on the pros and cons but I will say that they look awesome! Especially when they are that big because even though it's a 155 they just look so much larger IMO.
I have looked at a few and I can't ever remember them making anything inside the tank look distorted. I think you may be right about some of these issues with the smaller bows.
I sure hope you get only positive feedback because I'd love to live vicariously through you for a bit.
