I also run a Goliath and I don't think I will switch unless something that is head and shoulders better comes out. I love mine, lots of room, super quiet, very stable. I highly recommend it to anyone who wants to use a climber. Even if you are a little guy, the goliath is only one pound heavier than the viper, but you get a alot more room. I would also highly encourage you to get the side/front bags for you stuff. With the bags, I have eliminated the backpack.
