Well one of them needs to be your focus, since they are very different skill-wise. I suggest the first guy because he is actually a REALLY nice SF or inside oriented SG. 1v1 training for forwards sounds like a great idea. It will get you a lot of pops (In handling, jumpshot, driving, and inside shot) so I personally love it. Just make sure both of them get between 48-70 minutes per week and you should be set.
