Butterfly Timo Boll Spark vs Keyshot Light

Yeah, I am curious also about wood + arylate combination.  I have BTY Japanese catalog and it places both TB Spark and KL in the soft range with KL is faster compared to TB Spark, but both are still slower than Korbel.

But I want to know from the actual users, how these two blades played?

I've used both, but not extensively.  My training partner uses the Spark.  The Spark is a very soft blade for a composite racket.  Great for controlled looping and controlled blocking.  Lacks a bit of power to finish a point at mid distance, but doable.  I've own the KL, but have only used it a couple times.  Just tried it during my warmup at my last session.  I find that it's a bit stiffer and faster than my KLS, which is a bit stiffer and faster than the Spark.  Not sure if this is consistent across all blades as I've seen the Keyshoy Light listed as slower by Butterfly.

Ok, played with it more extensively today.  I have a 2.0 rather than 1.8 on the backhand side of the keyshot, so this probably threw off my impressions.  The keyshot light is slower than the KLHS.  I think the feel is a bit harder too, but still well in the soft range.
