I'm a dealer and I've sold almost all of the major brands. Ravin certainly makes a high quality bow, no doubt about that. Their range has been tested and confirmed, but as a hunter, I would certainly not be taking any shots on a deer past 50 or 60 yards. There's too much time for a deer to move, jump, and/or duck before the arrow arrives. Way too many variables for a 100 yard shot on an animal, at least for me. Personally, my opinion is the Ravin is more a brand/show-off thing. I know lots of guys that kill way more deer with crossbows that cost less than half the price of a Ravin. The name, technology, and performance is not what makes an archery hunter successful, least not in my experience.
Crossbow broadheads are another hot topic. Guys have their own brand and swear by them. Titanium is 100 percent not necessary for whitetail deer. It's really not even necessary for elk. The best advice I can give is to get one or two brands and try them out with your buy. Pick the one that groups the best with your bow and then evaluate it's performance in the field. If it flies good and cuts good, then stick with it. Personally, I like NAP Killzone mechanicals. The fly great for me and have always gotten the job done. A lot of guys like Rage and Swhacker also.
As for crossbow brands, I personally have shot several different ones and I always come back to Excalibur. They are dead reliable, incredibly simple, have been around for a long time, easy to work on yourself, and are dang near indestructible. I shoot a Micro 355 and I love it. I've found that it shoots Spynal Tap arrows incredibly well. I've had the Horton reverse limb models and even a few of the Ten Point models over the years. All very good bows, but I always come back to Excalibur. Something about shooting a recurve crossbow, no compound, that reminds of me Medieval Times. That and the fact that it shoots so darn good, I don't think I'll ever go with another brand from now on. But there are a lot of good options. Don't get hung up on the name or the "latest and greatest".
