KBS MAX vs KBS Tour Lite

Can someone please help me understand the differences between these two shafts? KBS MAX is 111g and TOUR LITE is 105g (Raw Weight*). I play stiff flex but I’m torn between the two. I hit a shaft with 105g and I liked the feel but want something slightly heavier. Don’t remember if it was the Tour Lite but it beats the 85g shaft that comes stock with the Stealth irons I got fitted. After playing some time, the 85g shaft is way too light for my preference. Saw the MAX were 111g. Sorry if this is a dumb question. I plan to get fitted. Just want insight/experience from fellow golfers on the performance, feel, etc. Any advice will be appreciated!
