Best cargo/passenger seat for 2016 sportsman 850sp

Well I just purchased my first atv. I went with the sportsman 850sp. I took it out this weekend for its maiden voyage with my 8 yr old son as a passenger. I know it’s not a 2 up machine but there is plenty room on there for a 45 lb kid. We rode 25 miles in pretty rocky pocono mtn terrain. It handled and performed awesome. I’m happy with my decision to go with Polaris. Now I’m looking for rear cargo with integrated seat that I can throw on when I take one of my kids and take off when riding by myself. I think I settled on the Wes industry models however I’m stuck between the comfort model and the classic. Does anyone have experience with these two models and can comment on them. Example: passenger comfort, front rider interference or feeling cramped. I know the comfort is larger and would be better for my wife the one or two times a year she would ride with me but does the extra few inches interfere with my back or push me towards the front in an uncomfortable position. I will be mounting it lock and ride so it can be easy off and on. Not interested in tail light or heated grips. Any thoughts. Oh and it might sound silly but the only reason I didn’t get the touring is because it only comes in red. Couldn’t do it.
