When you say "longer balance", do you mean more towards even like 12.8 in to 13 in? Just looking for clarification, thank you.
travlerajm said:The average balance for top-100 ATP pros is about 12.6", or about 7 pts HL for a 27-inch long frame. Pros with heavier racquets use slightly more HL balance. If you use the equation R = 44.6/sqrt(M), with R = balance in inches, M = weight in ounces, then about 80% of the pros have balances that fall within +/- 2 pts of the curve for that equation. And about 95% fall within +/- 4 pts of the curve. Also, if you plot career high ranking versus the number of pts above the curve, there is a trend where the longer the balance, the better the ranking.
match44 said:I am intrigued by your last statement travlerajm. Because the balance is longer also when the raquet is lighter as you can see when you plot the points balance vs. weight and where you can draw regression lines as you state with the equation R = 44.6/sqrt(M). I would intuitivily think that better players use somewhat heavier frames. So their balance point would from that perspective alone be expected to be shorter. It would be interesting to see whether - given the weight they use - the balance point for better players is longer than average for their weight group of shorter. That would also compensate for different setup styles like heavy/Sampras- and light/Nadal like.

Total weight really high with perfect balance, or
lower weight with 'longer than ideal balance?
fishuuuuu said:travlerajm, I'm confused. You wrote in your previous posts (I think) that a majority of pro players use a head heavy balance? Which setup do you think is the most beneficial for a hard hitting all-court type? (Please explain in layman's terms)
travlerajm said:I did not say that most pros use a HH balance. I said that pros use balances that are more HH than typical stock racquets. In other words, less HL, but still HL.
By far the best setup I have found is roughly the same setup used by many top pros.
Again, this has a weight of 12.45 oz, balance of 12.68" and SW of 365.
fishuuuuu said:I misunderstood, thanks for the clarification! That balance of 12.68 means it's roughly 12 pts headlight? How did you calculate your SW and balance?
travlerajm said:My balance is 8.5 pts HL (equivalent to 6.5 pts HL on a standard 27" frame).
SW is estimated by starting with the initial stock swingweight spec, than carefully adding the SW contribution of each gram added. For each gram (each square inch of lead), the added swingweight is m*(r - 10)^2., where m is the weight of the mass in kg (0.001) and r is the center of mass of that gram in cm from butt along the longitudinal axis.
The balance is simply measured by balancing with a yardstick.
