The Head Radical Pro and Head Speed Pro are both heavy tennis rackets with a focus on control rather than power so a player is going to need good technique in order to get the most out of these rackets.
This article will look at the specs of both rackets to see how they compare to each other.

Head Size
The HRP (98in) has a head size that is 2 inches smaller than the HSP (100in) so the HSP will have more power and a slightly bigger sweet spot.
Length
The HRP and HSP have a standard racket length of 27 inches.
Strung Weight
The strung weight of the HRP (332g/11.71oz) is 6g heavier than the strung weight of the HSP (326g/11.50oz), so the HRP will feel slightly heavier in your hand.
Both rackets would be categorized as heavy tennis rackets so they will not be suitable for beginners.
Unstrung Weight
The HRP has an unstrung weight of 315g/11.11oz, while the HSP has an unstrung weight of 310g/10.93oz.
Swing weight
The HRP has a swing weight of 330g/11.64oz, which is 4g heavier than the HSP (326g/11.50oz) so the HSP should be slightly more maneuverable.
Racket Balance
Both tennis rackets have a 6pts Head Light balance, which helps make these heavy tennis rackets more maneuverable when you are at the net.
Stiffness Rating
The HRP has a stiffness rating of 65 while the HSP has a stiffness rating of 62, which puts them both in mid range in terms of stiffness ratings.
Power and Control
The HRP and HSP are both low powered tennis rackets with more of a focus on control than power.
As you won’t get much help from these rackets in terms of power generation, you will need to have good technique on your strokes.
If you think you will need some help generating power on your shots, then the HSP is definitely the better of the two in terms of power.
In terms of control, the HRP is the better tennis racket.
Recommended Player Level
The HSP and HRP are best suited to advanced tennis players who have developed a full swing and have good technique on all of their strokes.
Beam Width
The HRP (20.0mm/21.5mm/21.0mm) has a thinner beam width when compared with the HSP (23.0mm/23.0mm/23.0mm) so the HRP will give you slightly more control on your shots.
String Pattern
The Speed Pro has an 18 x 20 string pattern, while the Radical Pro has a 16 x 19 string pattern.
An 18 x 20 string pattern will give you more control but less power while a 16 x 19 string pattern will help add more spin to your shots.
Grip Type
Both tennis rackets have a Hydrosorb Pro Grip.
