Here's mine, based on the criteria laid out:

1. Great Went
2. Cypress
3. Magna
4. IT
5. CBall
6. Lemonwheel
7. Oswego
8. Coventry
9. Super Ball
10. Fest 8

However, if we base this solely on JAMMING (and/or REPLAY VALUE), my list becomes very similar to the author's, with Coventry at #5, and with Clifford Ball dropping down to #8

1. Cypress
2. Great Went
3. Magna
4. IT
5. Coventry
6. Lemonwheel
7. Oswego
8. Clifford Ball
9. Super Ball
10. Fest 8
