I used sectional warping on my AVL Home Loom for over 20 years, and then when I sold it and bought the new David III, I stuck with sectional warping. My Woolhouse Tools 8 shaft table loom uses a regular warp beam. I like both methods, but if I am putting on a longer warp, or one with many color changes, I prefer the sectional warping method. It's faster and the tension on each section is identical.
I didn't care for winding spools and using a tension box, so I bought an AVL warping wheel. Love it and highly recommend that it's worth the purchase price. If I was a production weaver, warping 20 yard warps, then maybe the spool/tension box method would make sense. For me a 7 yard warp is a long warp.
I honestly enjoy every aspect of weaving and that includes warping, threading etc.
