coaming cutdown questions

i just got a sweet 68 ds1 and am trying to get it organized for sailing. i live next to a windy port royal sound and anticipate a lot of hiking. what are the pros/cons of cutting the coaming down? how is it done? if i cut it, how much coaming should i leave standing above the deck? thanks for responses, i saw little in the archives on this subject, tho i imagine it has come up before
