Diff Dilemna! Need opinions!

for those that already know, i know what the wheelhop was caused by...it was my pinion angle (another thread i had made was about that)...i believe the pinion angle mixed with possibly shocks not being long enough was the cause of the hop...because i kept launching with the hop, this was the result...its not the diffs fault, it was mine...the driver side hopped and its the driver side axle and side gear that had the most damage

as far as spools and suregrips go, id like to keep a stock style suregrip in the car until it wont last anymore, but im not sure how fast i can go in a stick car with one before grenading it...the car may not be fast now, but plans are for more power in the future, and id like to spend my money once and have it last...for sure no locker will go into my car...have heard too many stories of stick cars unloading during a shift and going straight into a wall because the locker unlocked...not something i trust, and this car is never going slushbox...way too boring...that being said, what else besides lockers and spools are out there that work well and are rebuildable?

like i said, i know for a fact my pinion angle is what caused the hop (3 degrees nose up...i know dont even ask)...ive reset it to about 5 degrees nose down, but i havent tested it out yet since i have the carrier apart (luckily i had a spare 489 cone style suregrip in the garage that i used to fix the problem) but im looking for a more long term solution as i still have a twisted axle

and in regards to the 6 cyl springs and my wheelhop, like i already said in the other thread im going to do things one step at a time...have seen plenty of guys run 1.60 60ft. times with stock 6cyl leafs, and i have a leaf added to mine...if i still got hop, i will go to the shocks...and if still after that will i only then go to fixing my springs...cheapest and more likely the cause first

havent tested out the new pinion angle yet, so we will see what that nets me
still interested in your opinions about what i should do for rearend choice...i already know the cause of my wheelhop no need for this thread to go off topic about how to fix that (another thread)

thanks guys!
