By the shul I daven in this Shabbos they have 2 kosher sifrei Torah (could be a third also?) they lein from (one big and one small.) The small one they always use as the "second" Sefer Torah. It was asked which one to use for Parshas Zachor. In terms of csav, hiddur, etc they are probably both the same. However the smaller one is older. Better to davka take the newer one or no difference?
In the end they quickly decided to use the smaller older one and save the bigger newer one for Zachor...To which the bal koreh said afterwards it was hard for him to lean over the bima and lein from such a small sefer Torah the whole kriah.
Any thoughts please share.
