So, my serving was great today, but I noticed more so at the beginning of my practice that my serves (especially my topspin kickers) were way more consistent than when I got in my usual "grooving" time. I think this may be attributed to the fact that items you hold for an extended period of time feel lighter and lighter as you hold them (up to a certain point of course). My racquet's weight seems more "solid" at the start of my my warmup than at the end, which may be because I need to adjust my timing for a lighter feeling racquet- and exaggeratedly so for my serving. Is technique the issue? Is the racquet weight an issue? Anyone else experience this? Note that I do love my c10s and I've added a couple grams of weight around 3 and 9 and have a flared buttcap along with an over grip, which counterbalance most of the lead, but I just wanted some input about this situation.
