These are not open finger, but Hatch Specialist are by far my favorite of the many gloves I have tried. There is a winter version too that I wore late fall early spring that are exceptional as well. Fit well, flexible, good grip, material on trigger finger makes for smooth casting.
$15 shipped w/ amazon prime for the extra large. They are worth at least double the price in my opinion.
