They are all good. You can't go wrong with any of them.

This is good to know. I'm using the 150 grain 4 blades for the first time this year and I can't sharpen to save my life.

Try a KME sharpener, with some good diamonds stones you can take a stinger/buzzcut way past shaving sharp! I've certainly seen a difference since going this route several years ago.  
 

They are sharp enough to hunt effectively right out of the package but I sharpen mine more anyway.  Ever since I learned how to sharpen knives to where they can literally split a human hair lengthwise, I've had an obsession with my sharp things staying SHARP.

You can hunt with them right out of the pack. I always strop them a little first, but that's just me.

The best I can do is get them duller so I don't mess with them until after I shoot through something.  

Ready to go right out of the package

Wicked sharp out of the package.

Very sharp - I just bought 3 packs, will be using the 125 grain 2 blade for Elk.

The 100 and 125 grain you can sharpen with an Accusharp. It won't work on the 150's because the blade is the same size as the 125's but with a larger ferrel to get the weight up.The Accusharp won't clear the ferrel on the 150. I use a little pocket carbide sharpener for those. Sharp out of the pack but I always strop them first. Killed critters with all three sizes, great heads.

Do you guys that strop feel like there is a good deal of improvement, or do you do it more for peace of mind?

I feel there is significant improvement and it makes me feel better and it's easy! [/b]
