Throw all fundamentals out the window, grip it hard, and heave ho! Really I am commenting because I want to learn the same thing. I get some pretty dry heads occasionally and I can't loft with any consistency

Lofting doesn't mean lifting the ball upwards and having it land hard on the lane surface, at least it shouldn't. 

Think about it.  If you hit up sufficiently to create that high loft you've added revs you usually do not want (if the lanes are torched) because when the ball finally does reach the surface it's movement can be more abrupt than before.  AND you've got a release that cannot be repeated with any degree of regularity. 

Ask yourself "why loft?"   If it's to get a little more length through the heads you don't want the loft to be created with your arm and wrist, as most who don't understand do, you want your LEGS to help you.  Imagine the jet landing smoothly on the runway instead of the crash of something else falling downward. 

Legs are for power and the arm is merely for direction.  I usually just pick up my momentum into the line with good strong footwork (more speed if needed) and then delay the release very slightly so I'm reaching outward towards the pins.  Extension with smoothness is what I'm thinking in my mind.  Loft can be your friend if you can repeat it, but can be disastrous if you can't. 

Next time you practice just try getting the ball out an extra 2 feet on the lane.  There's the old drill of laying a bath towel across the foul line sideways and clear it with the ball on each release.  Next, try moving the towel out another foot and getting the ball over it SMOOTHLY unto the lane surface.  And so on.  LEGS are your best friend in bowling.  Use them.

When done properly we typically don't need to get the ball 5 feet further down the lane, just a few.  We are only looking to delay reaction a few feet, and so you want your release as effortless and smooth as you normal delivery.  Good luck.

Thanks notclay.....you're right....I stand a little taller and push more with my legs. Also
I don't loft more than 2 feet or chuck the ball. It's more of a projection forward with greater distant than my norm.

I bowled on a sport pattern the other night with one solid reactive ball, and my adjustments were front to back. Later in the set, I lost more up front, and moving laterally decreased my margin of error and I left 10 pins and/or rolling 2's - which was iffy.

I asked this loft question cause, when I started lofting a foot or so to get further down lane and I noticed my rev rate had decreased. Though I was carrying better, playing in my comfort area longer, I thought I was doing something wrong at release. On THS I don't loft much, it's more lateral adjustments for me. So, I do need to practice more lofting. And I just want to know if I'm doing it correctly.
