Replying to Binding Questions

So I realized I have a question that the binding thread doesn't mention. I went into a shop today just shopping around for a new pair of bindings and the guy in the store mentioned that because of the boots I have (rubber rockered soles with at toe and heel) that I don't have much for options other than marker lords. so my question to the ns community is, are the market lords good bindings (I've always had marker and never had any complaints), and is that true that because of he toe piece I shouldn't be using other bindings? Any help?
