3 things for sure
1-spare shooting(i beleive hasnt changed much, if any)
2-synthetics
wood lanes are good for about 30 years, in our area(detroit) most are switching over to synthetics, which we didnt see many 10 years ago.
3-Oiling machines
It use to be-"when was the strip day" and the shot varied depending when was the last day strippped. With the new machines, most houses strip everyday as they oil.

Dont swing it-if you cant bring it
When in doubt-swing it out
