btx,
You have a couple of options of the balls you listed.
The Revmaster will start up well in the midlanes and give a very strong backend reaction. I would not hesitate to get that one......"if I were you". BTW---there are many of us out there that love this ball. I hope to find a NIB 15lber soon....broke my heart having to get rid of it when I dropped in ball weight.
The other I would go for if I could not get the Revmaster is the Bully, It will roll up a little quicker than the Revmaster, but I see it having less backend.
Just my 2 cents.
