Hey Bass
Did you drop or hit the guide? They are very hard and brittle. If there is something or place that you are storing your rod, or even handling, where it's not protected a replacement guide will crack again. Hope it's just bad one from the manufacturer.
Ridx that's awesome of you to fix it. Where do you get the ceramic guides without the metal supports? Angler_Brazil has a broken first guide. He leaned it against the sink and said it just tipped and hit the floor and the guide shattered into a million pieces. I'm sure he'll appreciate any help. I'll let him know or if you wanted to pm him. Thanks.
