The IQ Tour Pearl is going to be meant for medium conditions and it does have a nice backend motion to it. One of the common things that I have seen in league with people throwing it this year is that the Tour Pearl seems to be a little more condition specific and did not carry as well on house patterns. For example, lots of 10's being left and then some over/under. The people who have been throwing it for the most part mentioned they would not use it on a house shot. Tournament and sport patterns on the other hand is where that ball shines the most.
A suggestion for something that would be a bit more versatile is going with either the Cross-Road or Hy-Road. The Cross-Road is a medium condition ball, and is a stronger hybrid than the Wrecker. That ball is clean up front, and produces a similar motion, but will give you an extra few boards of room to work with.
The Hy-Road is another great hybrid, and would do the same. However, it's flexibility is that you can use in on medium and medium-heavy conditions (Cross-Road is medium). The Hy-Road has been on the market over 4 years now and it truly is a good benchmark ball to work with. This would probably give you the most flexibility in terms of what to fill on the medium ball spot.
So even though the IQ Tour Pearl is an ok ball, and unless you're regularly bowling in tournaments, I think you're better spending your money on the Cross-Road or Hy-Road. Both of those will be a bit more versatile and tend to carry better on house shots.
The Wrecker is a hybrid that's going to be a medium-light condition ball. It tends to go a little longer but saves its energy for the back. Based on what I saw with the video, I think the Wrecker will work for what you want to do.
To sum it up:
Medium-Light: Roto Grip Wrecker
Medium: Storm Cross-Road or Storm Hy-Road.
