Forza 4z was developed for those players who play a relentless topspin
game. The tacky and springy topsheet creates dynamic spins, while a soft
high tension sponge allows for superior ball feel. Forza 4z really comes
into its own when speed glued, generating heavy loops as easily as touch
shots. Made in Japan. ITTF approved.

Killerspin Forza 4Z Review:
Review: Forza 4z (MAX black) on a
TSP Balsaplus 4.5 blade
1. The reviewer:
Intermediate to high level club level player, modern defender (Chinese
style looper on FH). Blade TSP Balsaplus 4.5.
2. Physical Properties:
Simple but nice and neat packaging. Sheet looks of very good quality,
similar to other Japanese made sheets. It has a rigid adhesive plastic
protection sheet which reveals a soft and non-tacky but grippy and very
smooth topsheet. Measured hardness is 39deg (with respect to other
rubbers in the Sponge Hardness
Table). Most Japanese made sheets don't have plastic sheets
attached, expect a few like TSP/JUIC, so these sheets may be made in the
same factory perhaps.
Speed of the rubber is relatively fast, and feels quite linear like most
non-glue effect Japanese rubbers. Feels in a similar speed range to
Sriver/Mark V but a little faster. Rubber does not feel that bouncy, so
speed is not too high and very controllable in the short game. It comes
off quite fast on fast loops & smashes.
Spin on serves and chops is average, similar to other Japanese non-tacky
rubbers. On loops the spin was well above average, but not high, but
spin increased on harder loops. The makes it a good offensive looping/counterlooping
Even slow spinny loops are quite possible, as the topsheet feels soft
Control on this rubber is excellent. It feels relatively insensitive to
spin, similar to euro style rubbers with grippy topsheets. The soft
topsheet gives you a bit more dwell time, which gives you that extra
control when directing your loops.
6. Other Playing properties:
Throw of the rubber is fairly low to medium. It does not have any glue
feel or sound like a glued rubber. The sponge is firm enough to not
bottom out on even the hardest hits.
I'd compare the rubber to something like Mark V, but a little faster,
but the feel and control is similar, and durability is likely to be good
8. Other comments Other unique properties...
Rubber is not particularly unique or special, but is good for an alround
offensive style, and priced similarly to other rubbers in the same
catagory. Tuning or speed glue would probably give it that extra
speed/spin to stand out, but even without it it's quite a decent rubber.
