Ive used the tigersharks and love em. Never seen so much blood spilled with a two blade.  Every shark seems to fly dead on as long as they spin true which isnt a problem.

Hard to beat the tree sharks, amazing head!  They shoot great for me, 3 5 inch dura vanes, no problem out to 40.

I killed my Bull Elk this past September with 160 Glue-on Interceptor (non-vented) and then a Antelope buck with a 135 (vented) glue on Tiger-Shark. Last night I shot a WT doe with the Interceptor.  Had a great blood trail which was nice because I only sliced the bottom /back of the heart and got one lung so she went a ways.  My only negative is I dont like the noise (call it a whooosh) that all vented heads seem to make.  So I prefer the Non-vented glue on 160 Interceptor.  I think it may be the best of the bunch.  In flight...it is night and day difference between the noise these two heads make.  Game alarming noise!!!

My arrows are around 550 gn.  Bow is 54 lbs @29".  Steel broadhead adapters are used in 100 or 125 to make a 250 gn head plus aluminum insert.
Also...the 160 gn Interceptors actually weigh 150 although the owner said he may get them back to an actual 160 in the future.  Something in the grind etc reduced weight from the past heads. No big deal.  I like the 150 final weight anyway.

ive been playing around with the big treesharks, and have not noticed any noise with them.

I've shot Simmons heads since 1990, and have never noticed noise from any head, be it Interceptor, Landshark, Tigershark, or Treeshark.  Even out of compounds at around 270 fps.  I've also shot the original Interceptors, and Safaris, which aren't vented, and can't tell any difference in the sound.

No noise from my Tigersharks either.  Sweet heads!

Don't forget about the new TigerShark 175 gr. screw-in.    http://simmonssharks.com

I have hunted the Land Shark, Tree Shark, and Tiger Shark ... great heads and I do not hear any noise. The Simmons Steel Master is a great sharpening tool, even I can get a scary sharp edge on my Sharks with it, and I suck at sharpening !! For me much better than the steel eating wheelie sharpener, I really suck at that thing.

Just got to shootin some 2inch tree sharks today and they flew absolutely awesome!  With one doe tag left I cant wait to see the red snow!

I switched to Treesharks, and I've never been disappointed with them.  They leave some big holes!!

Their cost is not bad either!!
