IMO the strength and angle you can get out of toyota joints (oem toyota/lexus spiders is what I use) is unparalleled.WMS is 70 (pretty standard for a trail rig). I know a few locals that run narrower for comps, then add spacers for the trail.
I'm a Toyota guy....so the rear shaft will be 100% Toyota joints. The front will need a 1350 at the yoke, then Toyota from the carrier to the case. JE Reel is building with OEM Toyota supplier parts, and it's hard to beat the strength and longevity of their stuff. I believe the front driveshaft in my 1996 80-series is stock, with only 299,000 mall crawling miles on it (the rear has taken a dent or three, and runs a JE Reel with Toy joints now)
