In theory a 1:7 twist should be fine for 55gr bullets.

I suggest you do some research. In other forums there have been tests performed on 1:7 and 1:9 barrels side by side with 55gr loads. I think you would be fine with a 1:7 from a quality manufacturer to shoot 55gr bullets. But don't take it from me, check out some side by side testing to see what you think. There are resources that can tell you the optimum bullet weights with each twist. Some folks swear that 1:7 will not be optimal for 55gr bullets.

FWIW, I am going to be purchasing a 16" recon-style upper with an SS barrel once funds are available. I know I will be shooting from ~50grs to ~77grs through it. I will be using either a 1:7 or 1:8 twist.
