One of the very first rubbers that stating blending natural and synthetic rubbers. A traditional attacking rubber since 1970. It has been used in over 2 decades of major championships mixing speed and spin for the strong attacking game.
Was my first FH rubber long back. Even now occasionally go back (and really enjoy) to my son's (a beginner) Donic Waldner Allplay having the Mark V max in FH and Butterfly Sriver EL 2.1 mm as BH. A rubber with nostalgia and still reasonably excellent for funplay.
My favorite classic rubber along with Donic Coppa. This is an all time classic to be sure. I think too many players and especially developing or new players pass up this rubber in favor of the newest tensors to their game's detriment. As a developing players I used this rubber paired with a 5 Ply All+ blade and it really helped me develop my strokes and set a solid foundation to develop further. The control and consistency of this rubber is amazing and it has enough speed and spin for most recreational players. Recommended.
I use Yasaka Mark V on Yasaka Musashi racket (JPen). Actually this Yasaka Musashi racket was initially with Yasaka V-Stage but I felt it did not fit me very well and switched to Mark V.
Overall I find Mark V quite an "average" rubber - not particularly fast/bouncy, reasonable tackiness yet not affected by the opponent's spin too much, therefore generally speaking it suits an all-round player like myself.
On the other hand, the advantageous "average" spec could also be a disadvantage for more advanced players. Considering that more high performance rubbers have been developed nowadays, this orthodox rubber may not fulfill advanced players' demand. In that case depends on their requirement they'd better upgrade to other faster/spinner rubbers.
It's a pretty good rubber that goes much better with faster and more flexible blades. My Donic Persson Powerallround paired much better with Mark V then the Stiga Allround NCT (harder and slightly slower)
Incredibly durable as well. The sheet is still very much playable after 6 months of practicing 2-3 times a week. It still has a very good grip.
It's a bit hard though and the throw angle is lower. The rubber seems to be more suited for the older Backhand loop (more vertical) than the newer one. Perhaps the regular version of Mark V might be better on Forehand but anyone using an ALL or (ALL+ and hard) rated blade would probably find this a bit too slow after they can loop in match situations.
You can also generate a very respectable amount of spin, but you need a good touch for it.
This is probably the most stable attacking rubber out and was incredibly popular for many years in the sport. It has a strong mix of spin, speed and control all carefully mingled together. This was dubbed as the perfect rubber for developing and intermediate players at one point and is good value for money also. It's a classic!
I used this rubber during the speed glue era along with Sriver. These two rubbers were extremely popular during the speed glue era. The amount of control you had to ratio of speed and spin was perfect. The only problem is without speed glue you don't have enough speed.
Nowadays this rubber is very good for beginners and intermediate players wanting to develop their technique. I haven't seen to many players use this rubber any more. It use to be so popular! Those were the days...
