I like that bracket better than most I've seen used. It's an easy thing to make, if one has the shop equipment and some basic metal fab skill. That's one way of matching cable type & length. Going by your photo, looks to me like you have just enough adjustment remaining and that ought to be fine. Cables don't really stretch after being used for a while. I like no more than ~1mm of cable slack. IMO, that gives the best clutch action...especially with a stock-length CT70H hand lever.
