From memory, the bars in NL tend by and large not to have many brands, they're almost like tied houses in the UK.
I'd personally just be inclined to try as many different beers that I've never had before to be honest - if you make a hitlist will you consider it a wasted trip if you don't get to try them all? Some of them may be very difficult to get, and if you hunt them exclusively you will pass up on many otherwise great beers.
When I go back I try and avoid the ones I can get easily here too.
P.s. I was in weesp once. Ended up there cos I missed the announcement telling me to change trains <!-- s:( --><img src="{SMILIES_PATH}/icon_sad.gif" alt="
