Having used them for about 2 years now I have caught on them. Cant say if it's more than normal but I've had most of my fish in this period on them. Both the s2 and GPB2.
You still have to put them in the right place. If anyone decides that it's the bait's fault they haven't caught I would give your head a wobble. that goes for any bait. You just didn't put it in the right place at the right time. There is so many variables in fishing to ever be able to nail it to one single reason you didn't catch. You can only blame yourself for wrong decisions. Wrong rig, wrong hookbait, wrong spot, poor line lay, too noisy, wrong baiting approach, too many casts, etc. Throw in the variables out of our control such as temperature, weather, light, pH, water quality, spawning fish, natural food, oxygen levels. And then add the other angling pressure and what they are up to. These things change daily, hourly even. To say it's your hookbaits thats at fault is ridiculous to be honest.
The sheer amount of results that come to SHB means you cant deny they work and work very well.
I saw your posts in the other forum, you came across as a troll with some very poor timing as there had been some stuff go on literally hours previous to your posts doing the company down. I believe I told you that at the time. You may still be a troll who knows. Plenty banned from there for their part in rows, you played your part in getting yourself banned. I've been banned myself from there twice. Not sure why people think they get banned for no reason tbh. Have some accountability for your own actions. Ironic that you believe you did nothing wrong and got banned & that you blame SHB for reduced catch rates and it was nothing you did yourself!
