yikes if legs are needed for a better kicker, then I have to tap out...i'm going through a similar process...
i appreciate the compliment,... but similarly wasn't getting enough effortless rhs (need more legs).
this summer, i ran into a guy in a tourney that could kick the ball such that it would reach the middle bar of the back fence (and if were standing on the baseline, i'd be hitting a backhand overhead to return the kicker).
his main suggestions:
1. toss higher, let's me load more (legs, core rotation, hip out)
2. toss more directly overhead (vs. extremely left of my head)
3. use more legs to explode up (vs. mostly arm)
Although Jeff Salzenstein has a fantastic vid on kicker where he is hitting monsters without his legs and even comments on that! There is hope for the old hackers after all.
