Our impression
Hybrid shape between teardrop and round head with a large sweet spot: fibreglass face over a medium-hard EVA core with a soft inner layer – versatile for intermediate players who want to switch between control and power.
At 365 g, it is mid-range in our comparison – light enough for quick volleys, heavy enough to take hard balls with stability. Head shape Teardrop means: the sweet spot sits a little higher – more punch in attack than a round racket, more forgiving than a diamond; plus the medium balance as the all-round standard. The medium-hard core balances feedback and comfort. With power 5 and control 7 out of 10, it is clearly built for precision.
With a forgiveness rating of 6.6 out of 10, it is more forgiving than 72% of the teardrop-shaped rackets in our comparison. 5 of the 21 shops in our comparison stock this racket, with prices from €40.99 to €97.49 – a €56 difference for the same model.

Is the Siux Optimus 5 arm-friendly?
Not by our rule: the core is medium-hard, 365 g is above 360 g. We only call rackets arm-friendly if they have a soft core, a balance that isn't head-heavy, a round or teardrop shape and weigh 360 g at most. Suitable models are listed in our guide to padel rackets for tennis elbow.
