Those Running 3.73 And a TF w/ LockUp.. What's your highway Driving Like?

planning on getting a ranger rear to replace my small bolt pattern 7 1/4". my car currently has 3.23's with an A833OD and 26" tall tires. it feels most comfortable cruising at about 62-63, and 70 is starting to feel a bit buzzy. I'd like to get it to feeling about right at 70. first choice for me is a JY rear with 3.08's, 2nd choice 3.27
