This is a bit of a theoretical question but assuming you're playing against a NTRP 5 player, whats harder to use: a) A 98", 10.8oz racquet at 60lbs - 16x19, 300sw or b) A 90", 12.3oz racquet at 50lbs - 18x20, 323sw Assuming that you're hitting the same pace and spin that you would with either racquets over a 3 set match. The lighter racquet would appear to be easier but against a big hitter, you would have to generate most, if not all of your own pace since there is no plow through. Also, stability isn't very good. The heavier racquet would appear to be harder but against a big hitter, you would have a lot of "plow through". Not to mention that its extremely stable. Technique is a must for both racquets.
