Hi Dick,

Sell them both to me and let me worry about! ;)

All kidding aside...

Even a sporterized Krag has a history and any change that occurs to it changes it's history.

IMHO: You would be taking your desired carbine back to a time when it was originally configured.  Document it's history well and I believe when it comes to value or desirability...
You'll always find somebody who will pay top dollar for a 1896 configured Krag carbine (my personal preference) with a documented history.

We could probably go round-and-round on this subject and maybe money is not the issue...but what's your personal preference???

Whatever you decide I believe the majority will stand behind you sir!
