I am a HUGE fan of the IQ Tour - one of the best balls I've ever seen period.
I drilled up an IQTN about two weeks ago, for Nationals. The layouts of my favorite IQT and the IQTN are different, so keep that in mind for the comparison.
IQT - drilled pin above ring, CG kind of pointed towards my grip center. It comes out to be a 4.5 inch pin to PAP, and about 2 inches from my VAL. This ball gives me easy length and a pretty wicked move to the pocket. I've used this ball on literally all kinds of tournament patterns with good to great results.
IQTN - drilled pin next to ring, stacked CG, and a massive crater on my VAL, down from my PAP. It comes out to be a 3.5 inch pin to PAP, about 2.5 inches from my VALThis ball gives me more length than I thought, and has a VERY nice arcing motion. I've bowled with it on a handful of conditions, and it reacts best when there's a touch more head oil.
On a house shot, lining up with the IQT, the IQTN hooks noticeably sooner and has a smoother reaction overall. The IQTN is more like a rainbow shape and the IQT is much like a hockey stick.
On the same house shot, lining up with the IQTN, my IQT will usually just tap the headpin, leaving some beautiful 2-8, 2-8-10, or buckets.
So far, I've found it easy to adjust between both balls. Both are controllable and I know when it's time to switch. I like the 1-2 combo between these two balls!
I also own an IQTF, which sits comfortably between these two (I have no clue why, but I'm okay with this, haha).
I hope this helps!
