Well I had the same problem and well i talked to the other sailors and they all said the pluses and minuses and well to me i thought th aliminium polles are better because they dont bend why sailing unless its under alot of stress like falling in the water and getting caught but it all so has minuses like once bent you need to come in and bend it back and some are call ed hot sticks. Some people will say they are heavy but thats not all ways the case mine ways the same as pvi piping. Well if you do go for al have a spare in your sail box and make the end air tight so no water can get in to it. Well what ever you do have fun sailing.
