How do you figure out a rotation for a 5 man bowling team with seven men on it?

I have found that if a team uses their second highest avg bowler in the number one spot then the highest avg in the number five spot then third high in the number four spot and fourth high in the two spot and the lowest avg in the three spot works well. It would look like this:

1. Bob (202 avg)

2. Rob (185 avg)

3. Rex (173 avg)

4. Frank (198 avg)

5. Jim (210 avg)

It is good to have a lead off bowler as a pace setter and have a solid anchor bowler.

Hope this helps. Tom
