I'm tired of nearly getting getting my back nearly snapped in half when I ride across railroad tracks on my 2011 Ultra Limited, the HD stock air-shock are complete garbage so it's time to replace them. I already replaced the oil in them with a heavier oil and it still didn't make much difference, so I've come to the determination the HD air-shocks are simply a poor design. I've been looking at Progressives, which from what I've read are amazing--but very expensive. But I'd rather pay for a more expensive shock then have to deal with bottoming out every time I hit a pothole or go across tracks, etc. So here's my question. I've looked at Progressive 944, 444, and 412, they all see to be good replacement shocks, but I don't know if there is that much difference between the three. I'm a smaller guy (5'8", 157 lbs.) so I don't think I need a heavy-duty shock, but I don't want to bottom-out either. When I ride two-up with my wife we're probably at a combined weight of about 290, plus gear/luggage probably puts us at 320 max. But I ride solo 90% of the time, my sweetie only comes along on occasion. The price difference with these shocks is quite a lot (944 - $684, 444 - $612, 412 - $270), but is there that much difference between the shocks? I'm assuming yes, but perhaps not. Does anyone have experience with this? I know they're all better than stock HD air-shocks, but is there that much difference between these three? Will I be pleased with the performance of the 412 or is it less expensive for a reason--it's simply not as good. Or should I just get the 944 and be done with all this nonsense? Any feedback would be appreciated!
