Who has used this model? Is it just as quiet and packable as the alpha sit and climb? After using a sit and climb this weekend, I must purchase one of these. This seems to be the safest, quietest, most compact stand that I have been in. I am 6' 230lbs. I think the wider version would be better for me, especially when I am layering in the cold. Please give me any pros or cons about these two models. I have only climbed in one twice. I give it a big thumbs up, but I need to know what con I have missed? Thanks.
