I noticed that the CF200SE is about 300 dollars cheaper than the front zip design. I was wondering if it is worth spending the extra bucks for the self donning design? I know the disadvantage of the shoulder entry is that you need help zipping and unzipping, but is that the only reasons? I don't beach dive, would turbo soles be more comfortable or are the Rockboots a better choice? Sorry for the winded questions. Any and all opinions are appreciated.
