Working in construction you'd be surprised at the guys that have to carry around the LOOOOOOOOngest tape they can buy in their nail pouch. Too much freight for me. A 25' will do fine for most layout work that I do. I do keep a 16'/5M version handy for the odd metric project. As for the shop, the old standard and reliable Stanley 1/2" x 12' tape fits in my pants pocket & I can keep it with me all the time (no belt clip). I once pulled it out at work and one guy asked me if it came from my Mom's sewing basket. :gar-La;
