I go for Strange. That is what I run in both of my cars. I have the 40 spline setup in my dragster and 35 spline in my truck. I am switching gears and dropped one of my axles, it hit the concrete floor spline first and chipped the concrete...lol... Not a mark on the axle.
I have put plenty of passes on both setups and havent had any issues. My best advice is the get the biggest and best that you can afford. My rear is rated for 2000 hp and tranny is rated to 1200 hp, but my motor is under 750. That way I have some cushion... Hope this helps....
