Well, I'm not sure what optical stylet you used, but I can tell you about he shikani. I used it a lot in residency and was happy to find one in our dept. I like it. I'm the only one that uses it however... but mainly for the in between AWs that look ant. If I suspect a truly diff. AW, I go for the glidescope. Shikani are Def. good for ant. Aw's. Great bend distally. Don't forget to hook up O2 tubing to the side port. It gives you a little apnic oxygenation plus it really helps with the lens fogging up.
They are fun to use. 🙂
