MW
In my opinion either is fine. MW is more pricey, but what brand spool are You running. What I dont see is why You running 35 spline with that weight and horse power. I may be over kill but I went 40 spline all strange with 800 hp in a dragster. If Your buying new axles, and have a large enough 3rd member and housing ends, I would get the spool to match and move up. I turned away from a few high HP cars because of the 35 spline setup. Thats just me plus I think it will be worth more if You try to sell it. :wink: You can always sell the old spool and recoup some money. 8)
