I'm looking at some of these video's about doubles and to practice on things w/o rebound, how long does it actually take you to develop the speed that i see these professionals do...
Years ... It is not an overnight thing. As Cherri stated focus on control not speed. Speed is a bi-product of control. The more control you have the more speed you will attain.
The biggest thing is to have proper grip, find the fulcrum of the stick, do not choke the stick (hold tightly), use you fingers and wrists, allow the stick to rebound.

It is all about the fundamentals... it's all about basic control. The book Stick Control will get you wherever you want to go as far as control. Control Exercises can appear/feel boring/mondane if you let them but it is not the exercises it is you. You have to work with the metronome and master your technique and your body. The more you stay consistanly goal oriented and willing to learn the greater and faster you results. Steady is the course.
Apply this and watch your results.
