The standout feature of this blade is its good speed, spin and control. It’s the benchmark which all other carbon blades are based on.
Topspin: you get good dwell time when looping, very spinny and controlled at all speeds.
Counter play: again very good, plenty of spin, power and control at all distances.
Consistency: very consistent with all types of rubber.
Short Game: good for flicks, chopping, pushing, the lot.
Blocking: very good, nice and controlled.
Smashing: smashing is nice and controlled with plenty of power, no complaints here.
Feeling: this is where many players differ in opinion. I personally hate the feeling of this blade compared to other blades as it feels almost like glass, but I know others who find it okay. This isn’t good for developing players as feeling vibration feedback is helpful when learning.
Conclusion: the Boll Spirit is a very good blade which works well with all types of rubber, but really does shine with tenergy 05.
Rubber advice: tenergy 05 fh (max) and tenergy 05fx or 05 bh (max or 1.9).
Should you buy this blade? If you can find it, have the money and want a balanced, fast but yet controlled blade, then yes (most players agree the heavier blades 88g+ play better). If you can’t find this blade but want something similar then go for the Boll ALC, it’s basically the same blade but a notch faster and updated for the plastic ball. If you are a beginner and are learning to loop then I would go with a korbel, virtuoso, Nittaku acoustic or a slower carbon blade depending on your price range.
