Demos have arrived -- which one to try during FLEX league match?

[Unfrozen Caveman]

A batch of 4 demos arrived today. Tomorrow, I have my first USTA Flex League match and plan to use one of the demo frames. They are:

Babolat Pure Storm GT Mid+
Head YOUTEK IG Radical Pro
Wilson Six.One 95 BLX 16x18
Head Liquidmetal Radical

Which one should I try first? My current racquet is a Prince Precision 730 Longbody (Michael Chang).

All of the demos are strung tighter than I expected, although still not as tight as my Prince.

I care about trying to win, of course, but no so much so that I will just forego the demo opportunity. Which racquet is most likely to play similar to the Prince Longbody?

Not to state the obvious, but the PSGT + is the only one >27" long.

Switching to a shorter racquet in a match setting would probably induce a pretty rough acclimation period...

All of the frames are exactly the same length. Perhaps the midplus refers to the 98 sq. in. head size.

I'm not too worried about the acclimation period since I have only played about 9 times after a 14 hiatus. My strokes are not exactly grooved right now.
