Th3rty7 - The 2nd point may be a Susquehana. It's not a dead renger for the type but it's close. Plus is very appropriate for the region found. The 1st point I'd have to go with Adena and a very high quality example at that. As you mention it's not a typical Adena. If it is not Adena I'd then go to a late Archaic generic stemmed point.
Your question on type is always an interesting one to me. I'd say that 50% of my points I have a good idea of what type they are. Another 30-40% I don't have a defined type but I have thoughts on time frame based on any number of factors. The remaining ~10% or so are unidentified.
