You can get more help from you Pen if you use a guy like Nick Swisher ( Switch hitter obviously) off your bench for you Pinch hitter. Then one speed guy to run if you need it.
I think overall I have 4 95+ starters just in case and only 1 60 RP in my pen. Sure you might not need that many every game, but I like options based on how I think my opponent would do against certain speeds, release points..etc.
Also, still gives room for all 95+ lineup.
