90 minute boil for pm grain quantities?

i have a pm oktoberfest mashing on the stove at the moment, there is just over 3lb of pilsner malt in it, is it worth boiling for 90 minutes or should i just stick to 60 with that amount of malt?

Anytime you are brewing with Pilsner malt you want to boil it hard and long. Really. 30 more minutes of propane is a lot cheaper than ending up with five gallons of butter-beer.
