Babolat Pure Strike 100 16x19 and 16x20 are on huge sale by Tennis Warehouse Europe, I would grab the 16x20.
Neither Strike is going to offer that much, if any, more power or spin per unit spec than a TT 100 310. Decent pleener 100's, but not the right recommendation in this instance.
@seanyw - Having owned and played extensively with the 2019 TT 100 310 myself, and having tried all of the frames on your list, I think I've got a decent handle on this.
First, let's remind people of what you're used to: a 100" classically-oval-shaped, hybrid-box-beam pleener, with a very open 16x18 pattern. This combo plays very spinny, yet also decently controlled/predictable from the consistent cell sizing across the face and hybrid-box beam. Lateral stability and twist-weight range from very high (2019 version) to moderate (2022 version), and power-per-unit-hitting-weight is similar to a Dunlop CX 400 Tour (if the TT100 is the 2019) or a Head Speed MP (if the TT100 is the 2022).
All of that considered, if picking from your shortlist, I'd go
Pure Drive first and foremost, mainly due to having more TT100-like facial consistency than the FX 500, and a more direct feel and transmissive impact response than the Ultra, with the
Extreme MP as an outlier option,
if you think you may want to tilt your play style and/or mechanics towards a more spin-first approach. Additionally, if you end up favoring the Extreme for such reasons, you might want to give additional consideration to more options from actual spin silos — namely the
Pure Aero 100, which is class-leading and right up there with the Extreme MP, if not better in certain aspects, especially if you have the
2019 version of the TT 100 310, which is very similar to the Aero 100 in terms of firmness of flex, crispness of feel and high twist weight.
Hope that helps add some clarity. Any questions, feel free.
