I think the Tilt coaster would be good-if it was a standard looper, like Medusa, but had a Tilt drop. I don't think the Hammerhead Stall will do too well, either. I just hope Intamin 'U' impulse's won't become like the Vekoma Boomerang and be located at every park in the country. TPNE made a good point to me, that they are inexpensive, easy to build, and are good to add to a coaster count. I just hope SF only builds a couple more Imuplse's.
