I will still stick with 4.5,I think you can see a difference between a 3.5 and a 4.5 the way they acted. You just don't seem to see a 4.5 make the mistakes a 3.5 will.. But I also think it's makes a big differece where you are at, here in Michigan a 3.5 is equal to a 5.5 in other states because he has seen and avoid twice as many hunters in them 3.5 years than a 5.5 in other states.
