if you're looking for a flex board you should get a fiber flex, they are made by G&S there great boards and fun as fuck.
If you are looking for something in between flex in and stiff look at Rayne I ride a wayne right now and I love it, by far the best board i have ever owned. they are on the expensive end though.
If You are looking for a board with no flex get a Landyachtz I have owned many landyachtz they are very nice construction and extremely fun to ride.
As far as trucks go a good beginer truck are randall 180
