T and T long arms

I found a used set of T and T long arms. When I searched it looked like most are running that system with the frame stiffeners.

WHat do you think about running it without the frame stiffeners? Because if I buy it the budget will be busted and i can not afford the new stiffeners. They sell the upgrade kit without them.

Anyone running with out them?

Yes I am running w/o them. They're not needed to run the longarms but im sure they help.
