Agree the Townshend Seismic products are the way to go if funds allow, but if your budget is more limited I’d recommend these two options that have gotten very good feedback here and offer returns if they don’t work out. Personally I’d start with the Tough Nut cones unless you can only afford the Herbies Gliders. Just a couple other options, and best of luck.
