Replica Vs. Fish mount

[Super Spook]

Hey guys,
I am relatively new to the forum. Much more informative than any others I have been to. I have fished Big Lake for 15 years with friends and in my duck boat, but finally bought my first bay boat in February. I am really trying to get serious about learning this fishery and I learn more and more everytime I go. Read Trout Masters cover to cover. I have become addicted to catching big trout on top. I have good trips then the lake humbles me the next time out. I have caught about 10 6lbders and 1 7lber. Question- If I do catch a 8lb plus trout I would certainly like to mount it. How do the mounts compare? I assume for a replica you measure length, weight, and girth. Anything else needed? I would sure like to release the big girl, but just wanted get some opinions on the topic before I catch her.
