I want to move up this coming bow season with a better bow . I've been looking at the V-tec and the Slam & 1/2. What is the difference between the two? Any help is greatly needed!

The Vtec has different limbs( laminated ) riser and limb pockets as the biggest difference. The cams are the same from Hoyt to reflex except for increased adjustability with the Hoyt. No doubt you get more and better features with a Hoyt but only you can decide if they are worth the extra money to you. They are both great products.
