I'm not sure about Urethane.

I dont think Urethane would be great for say Nationals or on heavy oil. I just havent had great luck with Partical stuff, and thats why I was looking for a hard hooking reactive.

I havent seen anyone throw a Throttle/R so I was asking about it.

Get you a V2! Keep it sanded to 600 grit.

This has got to be the BIGGEST hooking Reactive ball of all time!

You can't go wrong with an Inferno. The coverstock is very versatile. Shine it up, dull it, sand it, no matter what you do, it still hits hard. Shined up it's a big hooker on medium conditions. Dulled down to 1200 to 1500 without polish and it's great on medium to medium heavy. I haven't thrown it sanded, but I know a couple of bowlers who swear it's a good medium-heavy oil ball when sanded to 600 to 800 grit. I know I prefer it dull over the Raging Inferno when I run into oilier conditons. I haven't found enough oil yet for the Raging Inferno particle ball.

In my experience, unless you have very dry outsides and/or very clean backends, the Throttle R is NOT a huge hooking reactive.  The X-Factors hook more, the Element hooks about as much in absolute terms, the Inferno hooks slightly more with a slightly more aggressive move off the dry.  With your revs and speed, the Throttle R will work better than it did for me (17-18 revs, 14-16 mph)if my experimentation is any clue.  But with your speed and revs, I'd be thinking X-Factors (and I'm not a big Storm fan).
