I use loc-line, but I'd recommend ULCS. The loc-line is floppy on the surface, though fine once you're under. The main downside is that if you get the loc-line long enough for flexibility to move the strobe substantially in all directions, it is unweildy. If you use shorter sections, it doesn't bend enough to get at certain angles. On the plus side, you don't have to loosen anything to adjust it, you just crank it over to where you want it-and it is cheap. OTOH, if you're spending hundreds of dollars on a strobe, another $100 or so for a couple of ULCS links and balls isn't going to break the bank. My new motto is spend early or spend twice!
