is anyone running these? Ive heard some horror stories about the previous model getting stuck in mud and stuck down etc. I see they have added a soft bottom mode to prevent this and also a stronger motor to pull the thing up. If you have the newer model what do you have to say about it. I personal like the 12' option. Is it worth the money? Has anyone had bad experiences with the new ones? do they work good in river currents?

Thanks all
