Set of sevens well played? 1 cent/2 cent

[Jaswarbrick]

Thanks Ranma. Do i raise this preflop like i did above for 4xBB + 1BB per limper, or do i just check this and hope for a set? I thought what was effectively three limpers with the small blind completing, to raise to 7xBB, or to check. Which is better option here? Because i probably have best hand preflop.
