it's a sketchy decision. luckily for us, so cal ppl, it doesn't rain all that much to where we have to worry about too much rain or flooding. if i were in a rainy city/state, i'd probs stay w/ a short ram. you really only have to worry about hydro lock around floods and all. not too much on light rain or anything, but i don't know how much rain you get over there. hope this helps a little.
