Funny that is how I would pick to shoot them too..
It is no secret that I love Win 70 Featherweights in 30-06, I had one until my son claimed mine. The Rem 750 carbine in 35Wh has to handle nice, but the trigger might be a little stiff how is the one on your rifle? Do you have a scope on the Rem 750 carbine? If so which one? The Marlin guide gun kicks like a mule, enough said. I have shot a Marlin Guide Gun in 45-70 and it wasn't any fun, I would compare it to shooting slugs through a 12ga. It had to feel good shooting nice groups through your rifles. Just ask someone you don't like much to shoot that 450 Marlin of yours for you.
