We have, turns out if you can drive with the grabber just above the tube and then bring it down and expand it you can get a good grip in less than 2 seconds. Of course you can also lower it into the center of the tube and then start driving away as you expand it and then its down to about a second. It was also a lot easier to align than anticipated when we mounted the grabber to an old 6 wheel WCD bot, which could be made even easier with a swerve drive...

That being said, I think in the end it'll come down more to execution of design rather than which direction you took. Since you already have many iterations of the pinch claw/roller claw concepts, statistically speaking you are more likely to execute a pinch/roller claw well than to execute an inside expander well. So in this case it seems like there are no 'right' or 'wrong' directions, just ones that you are more or less familiar with.
