i have a prinsu 7/8 and while I like it alot, if I had to do it again, i'd get a frontrunner or rhino rack, mainly due to the accessories (or in this case, with prinsu, the lack of accessories). Remember you are investing into their universe so to speak, more options for accessories, means less headaches for you.
Sure you can adapt whatever accessories you want to the prinsu, but running back and forth to home depot trying to buy the correct size carriage bolts gets old real quick.
also buying racks from boutique manufactures gets old real quick, mainly b/c you have to deal with their BS when it comes to delays, lack of customer service, lack of communication, etc. I rather buy off the shelf next time.
