Replying to Not centered skis

I recently made a thread saying how my bindings came off. I tried using some strong epoxy and putting the screws back in. It didn't work and I'm still waiting for my home mountian to open. My summer set up isn't doing me any good sitting in my back yard. I found a old pair of skis they are not centered but they are the size of my skis I'm going to use this season. If I use the non centered skis on my set up will it effect the way I do rails this season on centered skis? Balancing on a handrail is still balancing on a handrail centered or not. If this is not a good idea tell me so I don't suck ass trying to use my new skis. I lknow it's a long question and if you don't wanna read the whole thing skip to the 8th line. Thanks.
