Could n't comment about the JT 2 piece, but I have used a Boomstick for a little while and had no problems apart from the fact it is a little on the heavy side. One thing to think about when you go for a two piece is that fact that they are TWO pieces stuck together so somewhere there will be a join and if the join is not as seamless as it should be you will encounter problems. If you like the idea of a two piece system also look at the Freak system.
