I'm working on the lag effect of nadal's and federer's forehands that has been explained with lock and roll videos. You can also say "pull strokes" (I know you will never want to do that). http://www.youtube.com/watch?v=EMNtq393tvo http://www.youtube.com/watch?v=soADAL_uGs8 The problem is whenever i take a fully continuous and fluid loopy backswing, i can't feel the racquet going back and slap the ball. Whenever i give a hitch at the end of the racquet drop just before forward swing, after i make the unit turn i clearly feel the racquet going back and creating the natural wrist snap. This article also tells the same thing. You need to give a pause at its farthest back point to create the inertia lag; http://tennis.about.com/od/forehandbackhand/a/forehandloops.htm I agree that a huge loop adds momentum and power to your stroke but only if you have the traditional "laid back wrist" type of forehand. I mean if the angle of your wrist/forearm is set at the beginning of the backswing remains the same until the moment of impact, a big loop is a must because the more your racquet travels, you more speed and momentum it gains . But if you don't snap your wrist and expect the movement to do it naturally, your backswing has to have some sharp directional changes or pauses to create that inertia lag. So basically i think a loop is totally useless with that kind of stroke because when you give that hitch, you lose most of the momentum created with the loop. I wonder your opinions with that, thanks.
