I like the idea, also. Like several others I would not change every week. With the PBA Alphabet patterns so easy to get now, especially if the center has a Sanction lane machine, why run anything else. There are only 5 of those, so you could have the league choose which four they want to bowl on. If you have have a wick machine you won't be able to run "E" without some work the center is not going to go for anyway, so that would give you the four patterns. Sounds like a great idea for a summer league where guys are not as worried about averages.
