seriously, i think most ppl who get a heavy tripod just to counter stability problem during windy days kind of never encounter these situation much.
so far i never encounter any problem with wind in Singaporewith my slik 330dx with ballhead weight ard 1.6kg?
in fact most of my shaky photo problem when using the tripod comes from sea waves washing off the sand that i have set my tripod on
and like what edwin have said, its much preferable to hook ur bag on the tripod center column hood as and when needed rather than to get a heavy tripod.
for the sea thing, you dig your tripod legs into the sand, tada no problem.
just that you will get scratches from the sand... blah blah blah..
srini (asterixsg) - for such situations, i hold my tripod down....
