That's a stinking pile of garbage funds. With the 1 percent "pay to play" fee, you are really getting the shaft. I'm not sure it's worth doing this. If you have a $100,000 balance, it sounds like you are charged $1,000 for the "pay to play" fee and then another $1-$2,000 in fund fees. That wipes out most of the company match if you are making under $100k.
In your shoes, I would look at maxing out all my other tax deferred options, such as IRA's for me and the spouse. Then I might throw money at some taxable accounts, depending on my tax liability. Very few plans let you do "in service rollovers," which is what Solon is doing. Check into that to see if your company does, as that makes the plan more useful. If you can do in-service rollovers, check what the stable value fund is paying. If it's positive after fees, I might just use that to store the money until it could be rolled over.
Not sure how much you like your current job, but if a better offer came along with a much better 401k, I would think about taking it. And I would not be shy in the exit interview.
