interested in opinions about a KK hand
 

Friday night,borgata,2-5 NL.Average table.Two LAGs who were winning, nothing remarkable about other players.
I'm UTG with KK (about $700 behind).Table perceives me as tight.I open with$25-Standard raises at this table are 15-25.Six callers-very unusual to see so many callers from an early position bet.
Flop comes 2 3 4 ,two clubs.
$175 in pot,7 players.
I bet $300 with the intention of taking down the pot immediatly, or if someone wants to draw ,there pot odds and implied odds are now terrible.
Everyone folded and I took down $175.
Good move? Stupid move?
I briefly considered smaller bet($100-175) but was afraid of the loose player next to act calling and causing multiple callers which would tremendously reduce the value of my holding.
Appreciate any and all opinions.
