Well "needs" are all relative. In truth it isn't the need , but rather the "want" that most of us "need" to satisfy.
At one time or another, I've owned almost every standard stock, aluminium rail model that Excalibur made. I even briefly had a Vortex, but sold it, due to the short LOP of the thumbhole stocks of the past. With the Matrix line, that problem has been solved.
Currently, I own four Excaliburs, two of which have the older straight riser, they are smooth and fun to shoot. Of the other two one is an Exomax, and I just recently acquired a Matrix 405.
Having said that, the truth is that in over 24 years that I've owned Excaliburs, none have failed me. When I go hunting, I don't bother bringing a "back-up".
Sorry for being so long-winded, but I just wanted to explain.
Now to answer your question, do you need another Excalibur as a back-up...NO. Should you get one, if you can afford one, by all means. One can't have enough of them.
