Squadron Leader was the first English blend I ever smoked. Because of that, it has a place in my consciousness well above what may be appropriate for the blend.
It's a very nice middle of the road English blend. It's not too strong, it's very smooth, and it burns very well in just about any pipe. It could be a bit stronger, but I think it's just right for a lot of pipe smokers. The Virginias are pronounced and everything else is in the background. I wish the Latakia was a bit more prominent, but I really love Latakia. I've never really been able to taste the Turkish much in this blend, but the aroma is definitely there.
I have other blends that I like a lot more, but I could smoke Squadron Leader for the rest of my life and be OK with it. It's not the be all, end all, but it's a pretty easy blend to get along with.
