I just completed a rod for a member of the forum and had my first opportunity to use snake brand universal guides. The guides IMHO are all they are cracked up to be. The feet are even length, they are smooth so there is absolutely no filing or messing around with the guide foot. Just pull them out of the package and start wrapping. Because they are concave the do fit very nicely on the blank and the thread easily wraps up the foot. They are expensive but will only add $10-15 (max $20) to a build. There are a few manufactures using them but you will need to spend $700 on a rod to get them. The other part of the equation is Mike McCoy, the owner of Snake Brand, is a great guy. I am just hobby builder and have had the opportunity to talk with him a couple of times. He really cares about his product and our satisfaction. So if you have not tried a set splurge and give them a try.
