$11 TT w/2 limpers before

Felt chicken to just limp myself, and wanted to ask if raising preflop would be better. I guess my guts were telling me something, but I want to understand the why. TT just seems on the bottom end of a good hand...

Hero ?

As soon as I did it, I did'nt like the limp, but decided I'd bet the pot on the flop if it got to me.

Thoughts?
