Stick 50 yards or so of mono or AN other braid and try it again doing what you do now.
Chuck it out , wind it in and check the line where you have it around the clip.
sometimes if you wrap the braid around the clip a couple of times it helps to cushion the blow.
Possible as thats where it's always broke. Not had it long and only used a handful of times
Will have to take it down the field and have a few casts. Hopefully it's just a combination of cheap preloaded braid and user error. Maybe hitting the clip to hard. Was only casting 7 wraps
In that case it's the braid that's dodgy.
I've used all sorts of combinations in the past and I now just use 40lb braid straight through. Dead easy, no issues.
If you fix it to a wooden board with a lip it will sit nicely on the work surface, and can be taken fishing and sat on your tackle box.
Makes crumbing boilies easier and quicker than a Krusher
