rev rate vs. ball speed
« on: July 12, 2014, 11:27:41 AM »
how important is it that 2 things match up?
im not talking extreme differences, just more of the common types i tend to see.
knowing also that the higher rev guy will tend to show a slower speed on the lane because of how the speed is measured.

 #1 - 250 rev and 16 mph, should i try to increase my rev rate or slow my ball speed down?
Or can i just stay where im at and adjust with stronger layouts and more surface?

# 2 - 400 rev and 15 mph?

guessing in case #1 that it would difficult to slow the ball speed down and not very practical

i would think in case #2, you would want to increase your ball speed to get the ball through the heads better and store more energy.

thoughts?
do the elite players have these 2 items that match better than us average joes or is this not that big a deal

Until the game goes through another cycle slowing your ball speed is not the answer.  There are very few good bowlers who throw the ball slow these days.  Increasing your rev rate is difficult to do, but at 250 you aren't so low that you can't get reaction. 

There aren't many 400/15 guys around.  Rev rates over 400 are like guys hitting drives over 300.  A lot of people think they do it but few actually do.

If you get to watch a tour event or a regional with some tour guys the first thing you will realize is their ball speed is faster than it appears on TV and their rev rates are higher than they appear on TV.

going by the ball speed vs rev rate chart,

A 250 rev and 16 mph is pretty well matched.

A 400 rev and 15 mph is highly rev dominate.

do you have a link to this chart?
i have been 15.5 to 16 mph and 385 rev rate, recently i began to concentrate on a very loose shoulder and arm swing.
my ball speed is closer to 17 now and i dont know the rev rate now
i definitely have less ball motion than before and its much cleaner through the front part of the lane.
sometimes i seemed to have less energy at the pins and i was determined to stop having any muscle in my swing.
i may have use some more surface and stronger layouts if this swing change is permanent

300/17 is a good baseline.  +/- 50 rpm for every mph.

AHH, i see the ball speed on this chart is measured at the release point.
without CATS or something similar, i don't know how most of us can know that speed
is it 1 or maybe 2 mph difference from foul line to 45'?

If your lanes show speed,the rule of thumb is to add 2-3 mph to that.

You can use a video camera to figure it, it shows how here.

As long as the differences are ridiculous, like 12mph/500rpm or 150rpm/22mph, I think it's more important to match the equipment to your rev rate/speed.  A person who is heavily rev dominate should probably stick with lower hook potential gear, and the speed dominate guy could get away with using higher hook potential gear to get the same look.

Neither of the examples are extreme.  16/250 is fine, but might need a stronger ball on heavier conditions.  15/400 is more rev dominate, but a weaker ball or proper cover prep will get the ball down the lane easy enough.

This is a very good question.  First, matching speed to rev rate is critically important, but the ideal matchup is also dependent on the amount of friction available.   The amount of friction available on the lanes in the modern game makes it imperative that the matchup occur at higher speed and rev rate than may have been ideal in another era.  The reason is that the 3rd variable ( surface friction ) makes the matchup ineffective at lower balls speed, and rev rates on anything but the slickest conditions.  Because of higher friction rotational energy will be burned off at lower ball speeds no matter what the rev rate is.

There are other factors tilt, axis of rotation, that can alter how the ball reads the lane.

With the amount of friction available in todays balls I would rather be speed dominate.

But this is coming from a guy who is rev dominate now in his senior years and struggles with his ball reading the lanes too soon.

Scott - I've had pretty good luck lately with a RotoGrip Uproar. I haven't had any honor scores with it but it gives a consistent controllable look. I did win the city senior scratch all
events with it.

Interesting Randy I also used an Uproar last year after a Rumble.  The Outcry this year should be a good addition between the two.
