If I remember from my Engineering classes many decades ago, a tube is about 7/8's the torsional strength of a solid depending on material and thickness. Weight would be nice to know as well. a 35mm hollow may be about the same as a 32 solid, but much lighter. I just ordered a set of LG's. I know those and Phadt are 3 way adjustable on both ends. I know LG and Phadt are hollow.
