I don't think this qualifies as curriculum hopping. That is when you jump around and don't stick with something even long enough to figure out if it is decent or not. Have you looked at Math Mammoth? It is inexpensive, and you could use it along side TT or on it's own. The good thing is it is mastery based. So if they know something, skip it. You can work in your own review by doing the cummulative reviews. It really is a solid program. There are enough problems and different approaches to the same topic that it allows for some flexibility. What I did to move through some things quicker was combine years. DS needed to move faster so I would take say fractions, and look at year 4 and 5 at the same time and mesh the two. Not saying that would be the best for you, just giving an idea about the flexibility. One year builds on the next, so you really can use what parts of what year you need.
I hope this makes sense. I really cannot comment on CLE math because I am not familiar with that.
