I love flow. But sometimes the gimmick is cool enough to overcome a slight loss of flow.
In this case, the T-Rex will only grab the ball for certain modes, so not every time. The raptor pit becomes a way more interesting device, and as the pro catches the ball in the C lane, I am not sure the flow is any more or less between them. I wouldn't let "less flow" be the determining factor on this one as it seems to be very minimal.
