Ok heres the problem.
Currently I have a 3 speed xt crank. 44/32/22 paired with an xt cassette 11-34.
Now that I got stronger, I want to get an xtr cogset 11-32 and pair it with my 44/32/22 cranks. After this, when i feel im stronger again, I would like to upgrade my front cranks to the xtr 2011 3 speed set with a 42/32/24 xtr cassette.
We have a very steep hill here that I can climb with the 22 granny 34 cassette with some difficutly when i started. Now it seems easer for me to climb that hill thus would like to try the 22 granny with the 32 cassette.
When I feel stronger its time for me to go to the 34 granny with 32 cassette.
I dont want to go 10 speed since my shifting preference is still the x9 or x0 grip shifters. That plus the fact that 10 speed cogs are heavier (weight weenie here)

Shimano doesnt have 10 speed gripshifters and sram is still not sure they will release 10 speed grip shifters
So am I doing it correctly? 2 teeth at the time to let my engine get stronger? or should i just jump 4 teeths getting a 2011 xtr 24 granny and a 32 xtr 9 speed big cogset to conquer the hill from hell that we have.
Any help would be much appreciated.
