I had a 14.5" LW middy with a Moe handguard and an eMod stock and it balance pretty neutral. I've got another 14.5" LW middy with Moe handguard w/weaponlight and an Ergo F93 on it and it is butt heavy, but I prefer that balance. I think you will be slightly nose heavy with any of those choices given your setup. If you want something neutral balanced or tail heavy you may need a setup like a Magpul UBR or Ergo F93.
Looking at it from a choice purely based on the stock itself I really like the iMod and eMod stocks. Excellent cheek weld and very tight to the buffer tube.
