I was able to get to the local lake at around 3:30 today, and after making a few casts took this photo:
That's a 5wt rod, and I found that I altered between that grip and one with the index finger more prominently on top.
*Thanks for that link, Kelly. I always enjoy reading Gary and Jason's writings.
Looking at my photo along with Jason's grip, it would seem that my middle finger is lined up with the thumb in the 3-point style, at least to me.
