I also use baitcasters for pike and prefer them over spinning reels. With spoons, jerkbaits, and swimbaits, I'm casting 40+ yards with Shimano Curado reels and an American Rodsmiths Rod. I agree that 15-20 yards is very short especially with heavy pike lures. Make sure you aren't thumbing the spool to hard. Have you checked the braking system? Check out this video. It might help you out.
