NL10: KK in the BB

[crashzzz]

Both limpers are very loose and have been calling down some pre-flop raises, and the SB is somewhat loose as well...

Did I raised too much here? My fear was that the first limper would probably call with a smaller raise, giving the subsequent limpers decent odds to call after that, and I wanted to avoid a 3-way/4-way pot...

Should a 0.60$ raise have been sufficient in this scenario?
