Speed rebuy MTT strategy

im just wondering if any one agrees with my strategy and i would love to here some different point of view on how to play speed MTT's.
the ones i play in have a field of usually about 100 ppl,3 min rounds ,stack size of 2000 to start and the blind starts at 20/40.
during the rebuy period i pretty much play anything that has any potential.suited connectors,any two cards over ten.unsuited connectors.
if there is a raise in front of me i try not to get involved with a dominated hand like Ax or Kx,how ever i would if they were suited.
if some one goes all in,and couple of other ppl call,i would call if i thought i had two live cards.
say if 3 ppl are all in ,the pot is about 6K ,i would call with something like 45,suited or not,but i wouldnt call with say KT,or AT.
after the rebuy period,unless i have a huge stack i go to a allin or fold mode.
i would go all in with any two above T from any position.
im just wondering if others have different tactics,or what do you think of the above strategy????
