Bob;
If you can be somewhere between 5 1/4 to 5 3/4 lbs you'll be fine. Under 5 lbs might be too light to handle the wind----just guessing.
Tom Brett's original Perigee color scheme is the only way to go IMO---a very classy, tasteful combination of colors. I have used the dark blue wing bottom and transparent yellow combination before, and if there is a "problem" with that color scheme, it is that it is sometimes, just for a moment, it's hard to tell up from down, in spite of the dark blue wing bottom. It's worth it though
