I'll just go ahead and list all of my major Intamins:
1. Intimidator 305 (KD)
2. Superman The Ride (SFNE)
3. Maverick (CP)
4. El Toro (SFGAdv)
5. Storm Runner (Hersheypark)
6. Pantheon (BGW)
7. Millennium Force (CP)
8. Skyrush (Hersheypark)
9. Fahrenheit (Hersheypark)
10. Top Thrill Dragster (CP)
11. Sandy's Blasting Bronco (Nickelodeon Universe NJ)
12. Kingda Ka (SFGAdv)
13. Ride Of Steel (SFDL)
14. Cheetah Hunt (BGT)
15. Superman: Ride Of Steel (SFAm)
The rest are shuttles and family coasters
This list has me so excited for my trip next year. Will be hitting KD, SFNE, SFGAdv, Hershey and BGW. I look at that list and see as many as four 10/10 coasters for me.
My list is significantly less but I can confidently say that there isn't a bad Intamin that I have ridden:
1. Maverick - Cedar Point - 10/10 - This provides negatives, positives, laterals, floatiness, a punchy second launch and it is a long ride.
2. Millennium Force - Cedar Point - 9/10 - Great first drop, forceful pull out and a couple of good airtime moments plus a great sense of speed and it is long.
3. Matugani - Lost Island - 8/10 - Punchy launch, great airtime off the top hat in the back, hangtime on the loop and in-line twist and the first airtime hill delivers too.
4. Steel Venom - ValleyFair! - 7/10 - Great launches and this beats out Flash VV due to the holding brake.
5. Flash Vertical Velocity - SFGAm - 7/10
6. American Eagle - SFGAm - 7/10 - Good airtime and smoother than I expected which is good because it is a long ride.
