Which of the following cubes to buy for speedcubing?

[vaditya04]

I have researched for 2-3 weeks and haven't got any closer to deciding to buy a cube.
These are the following cubes I'm considering so please choose one of them.
If you think there is a better cube out there then please give exact link. Please don't suggest hybrids, I can only buy 1 cube.
By the way is cube4you AIR shipping reliable, if slow? Will it reach me for sure
( I live in India)? And can I pay using India credit cards?

What is the difference between a DIY cube and a Speed cube ( in www.Cube4You.com )?
Can a Cube4you Speed cube be taken apart and tuned JUST like a DIY?
Thanks a lot for answering.

I bought this cube a few days ago and it's amazing:

and CII is also nice if it's broken in and well tensioned

I also like the DII but it's not as good as the two above. I used the "old" Type C before and I also had Type A, AII, E, F, JSK, Storebought, Cube4you Cube.


I would definitely try all 3: CII, DII, FII.

Does the FII deteriorate?

 

[Swoncen]

Every cube does. I don't know yet how fast it will deteriorate because I just got it a few days ago. You better get 2 or 3 of them =)

I reckon you should never choose just one because everyone's preferences are different. For example I rate the C-II higher than the F-II, and I don't see that F-II as a huge improvement over an F, but that's just my opinion. That said I still prefer my C over my C-II.

If you can only get one cube, go for an A or a C (I'd choose C). They're both reliable and solid, conservative choices. If you can get more than one look at C or C-II, F-II, new A-III or cube4you DIY. I happen to think that the new A-III is the best out there, but it is also very light and feels fragile, so I wouldn't recommend it as an only cube.

New A-III is currently called Type A 3x3x3 DIY Cube (III-F) at cube4you. http://cube4you.com/product-589.html

if you get the CII I recommend using a C4U core and hardware. it's my favorite cube.

I also like FII as well. very light and smooth. I like the AI but it'a a bit slow. The C is a little too light for me and locks up and pops a lot. the C I also does better with a C4U core and hardware.
