I'm still pretty new to fletching, but having alot of fun and learning. I just recently finished up three batches to compare and contrast. 5" LW shields, 4" LW parabolics, and 5.5" LW bananas (the bananas were kindly given by member Huntschool...thanks Bruce!)
I've been playing around with these six arrows in my quiver for a couple of days. The shields and bananas are on GT Trad 3555's with 175gns up front (total weight roughly 465gns) and the paras are on Beman MFX Classic 500's, also with 175 up front (total weight 475gns). I've also been playing around with cock feather in and cock feather out.
I know for better testing I should have the paras on GT's as well, but I've really been wanting to try out the Bemans as member David Janssen had let me try out his and I loved the way they fly for me.
This testing is by no means super scientific, I just wanted to mix these six arrows into a few shooting sessions and see if any noticable differences (for me) emerged. Bow used was a 1970 Bear Kodiak Hunter 50@28 with a B-50 string, one pair of cat whiskers and felt pads on the limbs. Range was 15 yards.
This was my first use of banana fletching, and at first I was a little put off. I thought the 5.5" size was adding drag, but after my initial discomfort (which I now think was just a reaction to the visual appearance/size) these are really growing on me. They are flying great, and seem to be really thumping the target. I'm pretty sure I'm getting a little more FPS with these over the shields, but at this time I don't have a chrono to verify.
All three seem to give this shooter similar flight characteristics. For me, one fletch does not stand out from the others in performance. If anything, this amatuer test showed me that any of these fletching options would serve an archer just fine for flight.
As for sound, yes the shields gave me just a little more noise going down range. But I thought the increase was slight, though not negligible. For me the parabolics were whisper quiet to the point of being non-existant audibly. The bananas were somewhere between the shields and the paras.
While I would take any of these three to the field, I'm going to fletch up some more 4" parabolics (both on Bemans and GT's) for my fall hunting. I would like to try some low profile bananas next. I think they might be really interesting.
Thanks for taking the time to read this. I get so much information off this site that I wanted to try giving a little back.
