6wd - chain path revisited

[JHSmentor]

I am a mentor for a rookie team - hence, I am a rookie as well.

We have been researching 6wd systems and am curious what the pro's and con's are for the chain paths that could be used. I've included some very rough drawings (please don't pick on me too much over these!) to illustrate what we have been discussing.

I have my own ideas of some pro's and con's for these designs but would like some unbiased feedback so I will keep those to myself for now.

things to consider are drag created by the tensioners (if any), chain stretch even with the tensioners, dropping a chain, sprocket changes, wheel changes, stuff like that.

we will most likely be using as much of the kit parts as possible and filling in any gaps with similar or identical equipment - unless there are other cheap alternatives presented here.


thanks for the help!!

PS. the blue circles are the tensioners (still trying to figure these out), red are the sprockets, and the light blue are wheels - probably a mix of Omni's and kit wheels.
