soo our team is planning on a forklift design and we've had this sort of debate over how to design it (yeah we're still in the designing phase

)
my idea was to use the igus DryLin N slide system to make the side portions of the forklift
another person is arguing for using the DryLin S (the kind with a pole) with the linear bearing on it
Anybody have any suggestions/input on how/what we should do about it? I've never seen a real life forklift with the pole and the linear bearings but my teammate keeps suggesting it. Both of us argue that both systems have weaknesses (the structure of the slide system can bend since its open on one side sorta and the geometric structure of the pole is cylindrical, resulting in a shape thats not as suitable if force is applied on the side)
i would VERY much appreciate anybody's idea as well as other alternatives that me and my teammate havent thought of.
also, i was wondering if the igus Y.E.S. program will give us products that were not included in that goodie bag in the KoP such as the DryLin N80 (a larger version of the slide that we got) or the DryLin W
