I agree with Alex as he stated above, keep the stinger, if you're going to spend the money for a BK3, save that money and get you a Alex Brick, much cheaper and he makes them out of dymondwood. Stronger and little heavier than most break cues. It's actually a jump/break combo just like your stinger. Predator doesn't make a jump break, its all marketing. They want you to buy separate break and jump cues to get into your pocket. I try to avoid using predator products except for their exceptional chalk. The only really good product they have out there are their shafts. I've played with the 314's and they're super, but just more expensive than any other product out there. So I would suggest buying the alex brick first, if you like it, sell the stinger, if you don't like the brick, then just sell the brick to someone else and stick to your stinger. I personally like the stinger better than the predators, but if it was a choice between stinger and poison, I'd go with poison, but they also have a drawback with the short pin breaking or getting shoved into the butt more. Another side note, The bigger pin, IMHO, helps with a better break, its solid wood to wood contact. So 3/8-10 or a Radial pin will do just fine.
