The cost between the 2 is decent so I was curious if anyone has any comparisons between the 400r and 450r. I understand the 450r out performs the 400r but I'm wondering if spending the extra 50-70k for 2 x 450r is worth it or if dual 400r would be sufficient. I hear some with the dual 450r set ups can get close to or in the 90 mph range. Honestly I am not sure Id be comfortable going 90 in a pontoon, I would be content at 75, what kind of speeds should I bee seeing with 2x 400 r on a 25Sport C9 DC 3.0+ ( most likely Trifecta )
