I think my best piece of advice would be, settle into a math program and then stick with it.
Most programs will do a wonderful job covering all the important subjects and as long as your dc understand the math that's all that matters.
I think Saxon will be a good foundational course, but there are lots of great programs out there (as you know).
Consider your dc's learning style. Do they like pretty pictures, does that annoy them, do they learn well by listening, do they like clean black and white print, do they hate manipulatives?
See if you can answer any of these questions which might help you decide on a program. Also be prepared to put aside what you think is the "perfect program" because that might not fit with your child.
I loved Making Math Meaningful, but ds cried everytime I brought it out, so we switched to Math U See.
DD hated how plain MUS was so we switched to Bob Jones,and she loves it.
Remember, in homeschooling we can be flexible in what we choose to match our kids.
Don't worry about the "math-spaz", I use to have one at least once a year:willy_nilly:
