OK, I'm a complete noob when it comes to these things, I know there's a wealth of experience here so I've got to ask as I'll be buying more. I ordered my first swivel and the welded rings look a bit fugly.. Is this normal? Do I need to worry about it for a 150-200g rocket?
It looks like the weld is a little messy, but the integrity of the weld should be fine. I use the heavier fishing snap swivels on rockets that size, so your welded swivel shouldn't have any problems.
