Thanks for the input guys. I did use the term "short belly" in relation to the Rio
SHS line specifically because of the rod/line length ratio. The reason I brought up my recent experience with the Beulah Aerohead is... Looking at both manufacturer's taper diagrams, the two lines look similar in taper, and Beulah if I remember correctly, calls the Aerohead a mid belly shooting head that is similar to a scandi line taper. I was trying to find out if the two lines require a similar casting stroke. I use A LOT of underhand with all of my lines on both of my TH rods. I am very comfortable with my underhand dominated casting style. When changing from a scandi short to an aerohead on my 6wt switch rod, making adjustment to my sweep to handle the extra head length of the aerohead wasn't a problem for me. Every other part of my cast remained the same. I was hoping to hear that casting the Rio
SHS would give the same experience. The 230gr, 33' SHS sounds ok, but I really like the sound of a 40', 270 grain line on the 3wt... if it would underhand cast well. I don't want to drastically change my casting style and mess up my muscle memory.
Fly size isn't an issue here, I only had #16-#10 wets, #16-#12 dries and maybe the occasional #8 or #6 unweighted classic trout streamer or in mind. I already have a line system to handle the bigger/ heavier/deeper stuff.
I'm still learning here guys, be patient with me. I do not have access to any spey gear in my area unless I buy it. The guys I meet on the water almost always comment on how big my 3wt appears to them. I have never met anyone else fishing this way. Everything I learn about TH tackle is either through the internet or personal experience. I do realize I have put myself at a disadvantage (in line choices) by buying a 3wt switch rod, but the rod fits the majority of my trout water and fish size here in Central Pennsylvania. My interest in a longer line for the 3wt is because there are at least 3 larger trout streams/rivers within two hours drive of my home, stripping sucks, and long lines look cool! I have already made enough costly mistakes buying spey equipment, and want to make sure my next line purchase for this 3wt will meet my expectations.
My first costly spey mistake was impulse buying a 6wt switch rod as my first TH rod. It's a St Croix Imperial. It was cheap and now I know, not highly thought of in the spey world. Once I learned how, it casts and fishes fine for me. The action suits me just fine. The handle shape does leave A LOT to be desired though... it feels like gripping a baseball bat. I run a 390gr scandi short, a 425gr skagit, and now the 450gr aerohead on it. I had planned, and do, fish it for smallmouth bass, but its overkill (fish handling ability) for the vast majority of the bass caught here. I'm still going to fish it until its broke however. Had I done proper research and talked to you guys here at SP before buying, I probably would have ended up with a 13'+ 4wt or possibly a light 5wt for my bass rod. The bass water here is BIG... The Susquehanna near me is literally a mile wide! The typical fish I catch run 12"-18". I do catch a few 20"+ a year though.
Thanks again guys! You're all a huge help!
