Pure power speaking, I think is cab22. However, it's not a very forgiving racket. The feeling on an "off" day is rather frustrated...
ic, i bought the cab30ms and my friend is bringing it to me in early september, and i wanted a good smash racket!,
Used a Cab20 Power (Cab22) for about 10 years now and it's a great racket; it is unfortunate that it is so hard to find in the US these days. Tried a few Cabs over the years in hopes that they would match the Cab20 Power in performance and playability. Speaking strictly in terms of power ONLY I would say: Cab21 < Cab20 Muscle < Cab23 < Cab20 Power < Cab30 Muscle All the Cabs listed above are 2U. All are US version except the Cab30 Muscle which is a JP (The US version of the Cab30 Muscle is not availible in a 2U at the time of this post). All strung with Yonex BG80@22lbs except the Cab21 which was strung with BG85@21lbs. Same grips on all rackets. Note: Since longer rackets generally have a greater potential for power, for this comparison it should be noted that the Cab30 Muscle is a "long" racket at 674mm while the others are a standard Yonex length of 664mm. Cheers.
