I think the old PTC train is a better ride, but I honestly haven't rode in the NAD ones since the eary 90's, but if you don't want a beating dont sit in the very last seat the second dip can be kinda rough, I swear the downforce or g's are more than any newer coaster, also dont sit by yourself you tend to get bashed around a bit more that way. Its also been said that the NAD trains which were basically bought out of a cataloge sometime in the 60's so they weren't designed for the ride at all, and they are also suposedly about 100lbs heavier per car, On my last visit I was talking to some ACE members inline and also with an off duty ride op, who said told me that but I don't really thing the CLP Blue Streak was or is the painful kind of bashing like other coasters that can bruise you and leave you with a back ache and head ache for a few days. Definatly ride it at night though, you can see anything at all on the middle of the ride in the woods.
