oh, they can ruin "a shot" and force others of us to change.
The problem I have with crankers with eurethane is that they ruin my shot in three ways:
1. they scoot the oil out early in my shot as they cross my line going from left to right as I go straight. This often causes my ball to interrupt its skid early. You can see it jump a bit and it disrupts it's skid.
2. They change my break point as they come from right to left. I'm not always ready to have MY ball break when theirs has already made its move and charged across. Now my ball is disrupted twice.
3. They move oil farther down the lane. I'm already fighting long lanes, now they're longer?
Now - this said, it forces me to adjust. My problem is that I haven't found a way to make a solid adjustment to this yet. I'm not comfortable playing the twig (the only way to get far enough outside my crankers) and I don't have anywhere near enough hand to play inside them.
Best way I've been able to make it work is to take nearly ALL hand out of it, and toss it straight down 15 with a little hook action at the very end. Not satisfactory, not fun, but I can at least score.
