Swampman I just received my new Ten Point Titan Extreme and have the same questions as you, I'm guessing. Can't wait to shoot it if it ever stops snowing, BTW. What Xbow did you buy ?
Fortunately I have the voice of experience close at hand as my pard has been a Xbow hunter for many years. At this point in time I have opted to start with fixed blades and bought a 6 pack of 125gr. 4 blade Innerloks.
http://innerloc.com/secure/index.php?main_page=product_info&cPath=1_3&products_id=21Purchase was based on his input and the fact that he has put exactly 13 deer on the ground using these heads. Not too shabby.
I called Ten Point and was told that using 125 grainers would give me a slightly better F.O.C. using the supplied XX75 2219 shafts but 100 grainers will shoot just fine as well.
Just for the heck of it I will be ordering some 125gr Slicks as they have a great rep and their stubby blades don't plane as much as the big wing blades which is honestly second hand info gleaned from the internet.
