Well you just said given your image... thats great but the avg player on these poker sites dont watch players and have reads on players img's... you are in the 100NL but still ive experienced that many players dont really watch people lik ethey should because I hold a very tight table image and i still get many callers with mid pair when im holding ace high repping TPTK even two pair at times... And i used to get frustrated and I just realized a majority of them are fish and yes hold a table image but you shouldnt rely on it that much for your plays

Limping them with many people in the hand is +EV calling raises with those hands I find -EV because you base it on the fact that your TAG image will prevail...

hope my rambling helped
