my wife and I are New to the whole sledding thing but we are absolutely loving it, even with the low snow so far this year. My question to all of you is what size sled did you put your wife on? We live and ride in the Pacific north west. My wife is typ. 5'6 130lbs. Pretty agile. A new sled is not out of the question if it will help her out. her biggest complaint has been that she feels she just isn't strong enough to push them around. She has ridden a 02 summit 600, 01 rmk 700 and tried my 09 summit 800. I'm thinking about renting a rmk 550 that are new 2014's to see if that fits. I was convinced maybe a new summit 600 with the 146 track, But after looking at the specs the 800 is only a few pounds heavier. I know this is a pretty open ended debate but really i'm just looking for some direction from some one who has already been down this road. Thanks
