Your practice space should decide the ball—not the other way around. Answer 6 quick questions about room, safety, realism and feedback to find the practice-ball type that fits your setup.
Choose the location that represents most of your sessions.
Think about the usable landing area, not the total property size.
Compare realism with your need to limit distance and reduce risk.
Choose the feedback that would make practice most useful.
Use the most restrictive normal condition.
Pick the tradeoff you would be happiest using regularly.
A softer foam-style practice ball is the strongest match when tight-space practice and gentler impact are the main priorities.
Plastic practice balls fit a short-space training setup where very restricted flight matters more than realistic impact feel.
Limited-flight practice balls best fit a larger practice area where you want useful ball-flight feedback without full-distance shots.
