I am an amateur player and still trying to work on my ball placement and but alot of ball on the table so i am not sure what to purchase (Timo Boll ALC/Zlc) because I know that zlc is much faster than the ALC and i am worried that i can't control it . And on the other hand i am worried that the ALC will be slow and i will need to replace it with a faster blade
Issues that would need to be addressed before someone could give you reasonable advice about equipment:
--What blade and rubbers are you using now?
--How long have you been playing?
--You say you are an amateur player and a lot of balls go on the table, but what does that really mean: if someone was blocking for you, would you be able to loop 100 balls in a row on the table? If someone chopped HEAVY backspin at you, what shot would you use to return that with your FH? With your BH?
Do you have any video footage to show us so we actually can see how you play? It is really hard to give advice about equipment without having seen a person play. How could we know if those blades would be useful to you or not without seeing you play?
One last detail: it is worth noting how, at the highest levels of play, many many top professional players use blades very similar to the TB ALC, very few use blades similar to the TB ZLC. See if you can think about some of the reasons why that might be.
Lula gives good info. Merlin's info is good as well.
