I have both these balls and I am looking for advice on which one is the better starting ball. My Fusion hooks more then my IQ Tour so I am thinking ,start with IQ Tour and go up to Fusion or down to Hy Road Pearl depending on what I see. I have been starting with Fusion but if I need more hook the IQ Tour gives me less. I believe I have balls in the wrong order. A little surprised how muck more my Fusion hooks more then my IQ Tour. I was wondering if anybody else has the same reaction between the Fusion and IQ Tour. Just a little surprised my Hybrid is my most hooking ball.

Solid is smoother, Fusion is more angular.  Really no way to answer which would be better on a THS.  It is more about how you play the lanes and your style.  The thing about a THS is that it typically allows a lot of different styles to be successful.  If you like to get left and hook the lane, THS lets you do it, and Fusion might work better for you with a stronger recovery down lane.  If you like to play a bit straighter and stay out in the dry, no problem you can do that to.  Solid might work better that way.   

It sounds like you've made a decision, but let me give you a couple of pennies worth of advice. Be careful with the IQ Tour solid on house shots. If your house shot is actually tight and/or challenging, maybe you'll be okay. However, if it's the typical stand left, throw right, wide-open house shot most of us bowl on, I don't know if the Tour Solid is going to be the best ball for that. I find the IQ Tour Solid to be great when the lanes are tricky and I need control, but when they're wide open, the IQ Tour Fusion, IQ Tour Pearl (before mine cracked), and other balls give me better read, better shape, and better carry. Again, this isn't to dog the IQ Tour Solid. I really, really like mine when the pattern is tough; however, when they're wide open, I find that I don't get the right read and shape with it. I've had similar results with other benchmark balls in the past. Sometimes the balls that are best for control and read are the worst for letting it rip. Just something to keep in mind.

I agree with Gene - my IQ Tour Solid was the same. It was GREAT when the lanes were tight and/or I needed control, but I had much better options on a typical "stand left, throw right" house shot. Granted, not every bowler is the same, but that's what I saw with my Solid (which, while somewhat condition specific, I loved until it cracked).
