Need a Suregrip chunk. Stock, Powr Lok, or Tru Trac?

[KnuckleDuster]

Want to be able to spin both tires!
I know a used unit might be a gamble.
Tru Trac seems to be out of stock.
Powr Loc seems to be readily available.

Pros and cons?

Tru trac is super smooth. I use it on the road course. Power locks are rebuildable.

Trutrac in my 62 B body and it is very, very smooth. No issues laying down 2 strips of rubber and 8t is very quiet. Also no need for lsd additive in the gear oil.

Shows in stock from Summit Racing. http://m.summitracing.com/parts/dtl-913a572 Looks like it went up in price about $15 from last year.

TruTrac is an awesome carrier. I would highly recommend it.
