Congratulations on a beautiful bass.
Replicas are awesome, I have 6 and they are great ways to acknowledge a big bass and give you something to strike up conversation to tell the story when folks come over. Being replicas they are easy to clean too, just pledge and a rag and they look like new again.
I am part of an organization called Bass Life, here in NW Louisiana we hold a fund raising banquet. Through the year we provide replicas for angles who catch weigh and release big bass. We pay half for an 8 pounder, 3/4 for a 9 pounder and 100 percent for a 10 plus.
These weights are regional obviously... Whether you should get a replica is up to you, I say heck ya!!!
Cost, we'll be pay about $350 each, we get a break because we order so many. If you have a local taxidermy, check with them. I know BPS does it but it seems like they are pretty expensive. All this rambling to say it's not cheap but I'd do it if I caught one that big in your neck of the woods.
