No one can make a hard determination on your behalf as to which mics YOU will like best for overheads. We can only make suggestions for ones for you to audition. I suggest you continue to research the issue and develop a short list, then arrange with a professional dealer to get ahold of them and do a listening shootout in your own room.
I happen to use the C42's almost exclusively as overheads - both in my own room and when doing remote live recordings. I tend to use some variation of the Recorderman 2-drumstick configuration (although I tend to use a slightly longer distance) or else a coincident-pair configuration - depending on the kit and the style of music. (Sometimes on "live" gigs I just use one pointing straight down at the snare as a mono OH). I have a pair of 414's, but since I like them so much on Toms, I don't tend to experiment with them much on overheads - but they are a classic favorite with many top engineers as OH mics.
The other consideration, though, is what mics will round out your collection the best. After all, these mics are not always going to only be used on drums - assuming you record other instruments as well. If you don't have any small diaphragm condensers yet, they are very useful creatures,and that may influence your decision towards the C42. If you are unhappy with whatever large diaphragm condensers you have, that would argue in favor of the 414. Both of these are very versatile mics that will see constant use on a variety of sources, which is why I picked those two in particular.
On the other hand, while you may find a few things the SolidTube is good at, I would not call it a versatile mic in the same sense as the other two. If you got an incredible deal on one, it might be an interesting way to round out a collection, but there are plenty of mics I would buy first, and buying two of them seems to be a bad allocation of resources.
If for some reason you absolutely can't figure out a way of trying before you buy, the 414's and/or C42's are still good choices for the following reasons:
1) You can always use them somewhere on something, even if you eventually replace them on OH's with something else.
2) They are always going to be people looking to buy them off of you if you don't like them.
