|The option with the long bolts obviously needs fewer holes in your plate and that is one of the reasons why I chose it. The downside is that it is difficult to align the holes and to assemble the whole setup. I'm not sure if it will be easier to assemble the short bolt option. Could be more flexible, but I found that I don't need a lot of flexibility. I do not change anything for years so flexibility and fast dis-assembly/assembly is not that important to me.
