Please help me answer some of these questions! (When I say 'closed' I mean a couple of degrees). 1) The majority of baseline rally shots on the professional tour are hit with a SQUARE face. Even the claycourters like Ferrero do so. True or False? 2) Heavily spun angle shots (eg. passing shots) are usually hit with a CLOSED face. True or False? 3) Is it possible to hit a ball that has a low trajectory (let's say around 2 feet above the net), which is heavily spun with topspin, is fast, and lands deep, with a SQUARE face? aka 'heavy balls'. I actually don't think this is possible with a square face because the harder you hit, the more spin and pace you'll get, BUT, it would also launch the ball up into the air a fair bit, would it not? During warmup I always hit flattish shots with a square face, and it's very consistent, but it's with about 70% of my max swing speed. When it comes to the match, I will take swipes at the ball (85% or so speed), and hit with a closed face to make sure it doesn't sail out. Bottom line: For me, it just doesn't seem safe to hit with over 80% of my max swing speed and try and hit with a SQUARE face. I want to hit consistently with full swings, but don't want to hit moonballs. I want to hit balls like Coria for instance. So, is this possible with the vertical plane?? Thanks!
