Hey thermo do you have a pic of those new vanes?
I use Grim Reaper's for deer,also shoot ST's and Montecs.I like the larger cutting diameter they give me.As for tuning,I have seen alot of people on AT not tune for fixed heads as well,just adjusting their sights.
i dont have a ton of experience, but anyone consider wind deflection to be an issue with some of the larger fixed blade heads?
I like expandables for marginal shots that are to far back. Better chance of clipping the lungs. For some reason I dont miss deer to far forward, usually to far back. Just a thought
Why risk the shot of your lifetime to something that (may) work. I take pleasure in tuning my bows to the place where the broadheads (Magnus 4 blade Buzzcuts). field points and bare shafts will all group to the same place at 20 yards. That said if I wanted a mechanical broadhead I wouldchoose the simplest design I could find. maybe the NAP Spitfire. As I am only pulling a 50lb bow I feel a good fixed blade cut on contact stuck in the right place is the only way to go. No broadhead will make up for poor shot placement, or as the instrictor said "make the first one count kid".
I wouln't say wind deflection. I'd use the term wind drift, which is probaly what you meant. If so, I'd say it depends on how far your hunting shots are. Under 30 yards it's going to take a pretty brisk wind to blow tem off course. I would say that if the bow isn't tuned well or you blow the hot and the arrow comes out of the bow ugly then those bigger blades are going to catch more air and can veer off course badly.
I learned a long time ago that vented blades can help with this, but a narrower cut head almost ensures good tunability and flight. It all just boils down to the surface area of the blades, alignment of the heads with the shaft and how well the bow is tuned. A head with a cutting width of 1 1/16" kills just as assuredly as a 2" width when put in the boiler. And usually that narrower head will be easier to tune, too.
wind deflection came to mind because last year was my first year archery hunting, and on the first evening of the first day of the season; we had wind gusts of up to 40 mph, rain, and steady wind of at least 25mph.
Being the first day of the season I couldnt miss it, so I went duck hunting in the morning (perfect ducky weather), and went out archery in the evening. 8 minutes before legal shooting time ended a large 8 pt walked up behind my treestand, I was getting ready to get out of the stand when I saw him.
Missed the shot, not really due to wind, although it may have been a factor; but the low light ruined my shot, and I hit a limb that I didnt see. Anyway I always look back to that moment and wonder if the wind was to strong. With that said I wouldnt have made that shot with a mechanical or fixed.
a overlooked aspect of them too is the sheer "potential" and "perception" of them. "potentially" all the advantages they have , at least from an advertising standpoint, make them at least to half the people that are interested in a new broadhead , psychologically certain that mechanicals are the way to go. obviously the vast majority of them work well on deer size game most of the time. once consumer confidence grows in a product that people "just have to have" or "becomes the next rage" ( no pun intended), then the consumer is at the mercy of the manufacturer and then they can charge whatever the market will bear (which is why many folks refuse to buy them). that in turn creates the perception of if it costs more it must be better which leads many folks into buying products like mechanicals because it makes them feel confident they own the very best they can buy or afford. on that thought this isnt declaring mechanicals inferior/superior , just explaining a different side of their success story.
It doesnt surprise me that a many of mechanicals biggest fans are shooting >$1,000 "big 3" bows, or toting around a 45$ bottle of doe in heat .
