I agree with the above - if you REALLY "get" the GMAT, it won't matter what test you take. For example, I'm sure you'd score upper 40s/50s on quant no matter which company's test you took. If you can run a marathon, you'll be fine whether you're asked to run 5, 10, 15, or 20 miles...
I wouldn't totally freak out about the low verbal score at this point, but you clearly know where your weakness is. Now that you've been abused a little, use this as motivation to get that score up.
Happy studying!
