Hey guys, I'm looking to take my girlfriend with me out for a ride this year, and I was either going to put her behind me or sitting infront of me on my IQ 155. So I was wondering how well this would work. The both of us together are probably 270 together, so if heavier riders or people who have doubled up before have any advise for sitting the sled up to handle this? Also, anyone have any idea how much the extra weight will affect handling/power? It is only a 600 after all. thanks!
