These vacuum rod holders are popular in the pacific northwest and although they are way more $$ they allow selective placement of the rod holders on any vehicle. This is especially useful when moving from river pool to pool with Spey rods 14-16ft in length. In such cases it is clearly better to have the point back, on topic.
With short stout singlehanded SW rods moving from beach to beach I don't think it really matters - although I am habitually a point back thinker from years of bushwacking through dense forests to get to select pools on rivers out west.
I know Kush and others in the PNW are firm believers in these vacuum mounts. Redington now sells them for $125. If they were a little cheaper I'd have them on my truck right now!
