Two simple 6max preflop questions

[punter11235]

Open raising any pair from any position is the way to go, right ?
Raising any pair from any position after any amount of limpers is little too aggro , right ?

Iam doing both recently and it seems to yield good results.
Oh, and for "you need stack sizes and so on.. to answer this kind of questions" kind of guys assume that everybody has 100BB and its typical Party 6max 600 or 1000NL

Best wishes
