Lockers smockers, learn to wheel properly and use the skinny peddle effectively and you don't need them unless your crawling around on some huge pile of rocks.
So after reading this statement I gave it some thought.
And in the end I have to say that I think that your statement is poorly thought out. Now maybe you don't need lockers, maybe you do. But your statement implies...........at least to me that because I use my lockers that I don't know how to wheel properly. I am unsure how you can make that definitive statement against everyone that wheels with lockers. Seems to me that it is about as logical as saying you don't need four wheel drive to go wheeling, by your logic 4wd isn't needed just someone who can wheel properly and use the skinny pedal effectively.
Lockers like any other equipment (bigger tires, stronger axles, lower gearing....etc etc) when used in conjunction with good technique can allow you to tackle terrain with less risk of mishap or damage. Now I have no problem if your statement was something along the lines of ...............You should never drive beyond the means of your experience or equipment (or better yet the combination of both), but to just outright state that having a piece of equipment that allows for a different approach to obstacles is only needed if you don't know how to do something properly.........well I think that is a single minded opinion that does little to provide any insight.
I have seen plenty of situations were lockers were of great value and it was more than just crawling around a huge pile of rocks. I have seen plenty of situations were more skinny pedal just means more damage. I 100% agree with the experience part, and there are many spots that I have come across where I am pretty sure my equipment could have done the job I don't quite have the confidence in my experience to tackle it..........so I go around.
For climbing, descending, mud, snow, rocks, water, ledges whatever.......................give me my lockers................if that makes me a poor wheeler then so be it, I can live with that.
