My friend just bought a T-5 kit from Toomey a couple months ago. He loves them. We ride them on alot a trails, hilly stuff and just alot of field riding, trail riding, about anything you can think of, and they suit him just fine. He is running stock gearing with 20 in razr's and has no bottom end problems what so ever, and they scream uptop
They sound great, but almost unbearable when next to him, and he rips it. With the helmet blocking most the suond it still hurts my ears.
As far as the rockets I love the loook of them, but have personally never seen them, or ridden them. So I cant give you an opinion on them, but I would bet either one will make you more than happy
good luck
