I know that bottom pictures can't tell you much, but here are some opinions on how this rod behaves. I tested the rod with various 4 and 5wt lines and it can be described as a strong 4 or a 4/5wt rod. The tip specs are progressive and dampen quickly. While the rod casts a long line, it will throw lovely loops at short/medium distances with various 4wt lines-perfect for your standard dry fly presentations.
If you like little more feedback in your cast, slightly heavy 4wt lines (various Airflo, Rio Gold or SA GPX) work great. This would be a nice all-around choice when you need to swap a dry fly with a weighted nymph or a bugger. When you want to go for more distance, the glass butt section goes into play and with more line out, the rod starts to feel semi-parabolic, with that extra kick coming from the fiberglass butt.
Using 5wt lines on the rod will get the butt section engaged sooner, with less line out, but without the tip collapsing. Anglers who like deeper loading and more feedback from the rod might actually prefer it with a 5wt line.
The rod will be tested on a fishing trip to Driftless Area in a few weeks, so more details will follow on how it behaves in real fishing situations..
