I have been using the “lighterPack” spread sheet online. Is there one, similar to this that I can download as a template for use on my local Window device, WIN10 (XCEL 2016) ? There used to be one on the Backpacking Light web site. Yes I am willing to pay, nothing in life is free, I just cannot find one that is nearly the same. Microsoft does not have one online, and most of the others are check lists only, with no weight calcs within the formulas for each category of items. Any ideas on this one ? There has to be one out there, and I am too old to do it myself.”
