I have been using the same set-up (TH-D7A + Arrow satellite portable ant) 
successfully with AO27 for the past several months. Have your HT 
preprogrammed to compensate for Doppler effect on the 70 cm downlink. 
Also vertical polarization seems to work well with this bird. 

As far as the 'big guns' are concerned, they are over on this side of the 
pond as well. They don't know the meaning of QRP -- high power seems to 
be prevalent here as well even though it is unnecessary and probably a 
psychological prop. I would advise to wait for a lull and jump in! 

I am sure you will have great success and wish you much luck with this 
bird.
