Hey TrippleB, saw a post awhile back regarding all your Dunlops. What one did you find the plushest? I have a relatively new Aerogel 300 4D and my elbow gets sore if I'm swatting flat ones. I added silicone in the handle, lead at 3&9 and still it fatigues my arm. I do love the play it gives just wondering if M-fill or the 300 before the 4D were sweeter and more arm friendly.
