I have been playing with I-Pres for 2 years now and have grown so attached to it I cant imagine switching. My coach says my swing is huge, so, if you swing big, I-Pres is for you. However, remember not to string it higher than 55 pounds on mains, it makes the stick play like a board. Its got tight pattern, so anything below 55 is good.
PS I-Pres is not a small hitter, so, if you feel that after demoing it you are still smashing holes in the fence (I am having a hard time imagining anyone do this, but its possible) try Yonex RDX 500 mid. That stick is all about " do the work yourself, all of it, all the time".
