The Jollies Thrust unseated the larger Fun Factory Curve as my very favorite thrusting toy, proving that size really doesn't matter, it's all about the motion. The unique shape of the Thrust allows for quite a bit of variety in motion, both in depth of penetration and the speed of the thrust, and it focuses its attention the g-spot.
Once you figure out how best to hold the base -- I found the bullet hole to be quite useful as a handle, and the base is quite substantial on its own if you try using a bullet -- then I recommend taking the time to explore the options the Jollies Thrust has to offer. Rock it against the g-spot, or try rapid, shallow thrusts to massage it. Or thrust with wild abandon. It all works.
As for the bullet hole, it's the right size for the Jimmyjane Little Chroma, which can then become a vibrating, if awkward, handle, or it fits the bullet that came with my Tantus Echo quite nicely. The silicone transmitted the vibrations adequately. For intense vibrations, hold something like the Mystic Wand against the base.
Overall, the Jollies Thrust is a versatile and satisfying toy.
