IMHO, just pick one & build it. Don't worry about it being PC, HC, or anything else, learn to build one first & get to shooting it. Then if ya want to get all PC & HC, you can work on that as that most likely will make it a much harder build. Lots of times when you go for HC/PC the parts are not avail & you have to make them, = allot more work & very trying at times to say the least.
Pick one YOU like, get some decent wood & go for it. You can think this thing to death & I guarantee ya no matter what you do, you will find things you would have done differently later on.
I suggest ya go with a reputable dealer, such as Chambers, or Dunlap, or Pecatonica. All three have decent stocks & parts sets & back up what they sell. Chambers will be the most PC/HC, but will cost more.
