Favorite b&m's are batman the ride, kumba, montu, raptor, riddlers revenge. Sub 2000 installs. I have ridden every b&m hyper in north america and the airtime lets me down. Most are smooth.
I guess the reason I like intamin so much is that their cookie cutters are mainly built overseas. Here in the states the installations are world renowned and all are original: maverick, ttd, mf, supes, bizzaro, i305, el torro to name a few.
To me all the b&m's built in this millennium are all cookie cutters.
