Generally it is not as simple as replacing the 12 for an 11. As CX says you will create quite the jump. Usually you replace the lower half of the 12 cassette with the 11 cassette so that you keep the 11-12 jump,but you will loose the 14t cog giving you a big jump between 13-15.
Your cassette will go from:
Only you can decide if you need the 11t cog more than the 14t.
As you mention I was going to ditch the 14 and make the cassette into what SRAM sells as a 10 speed 11-32.
I am switching from a 52-39-30 triple to a 50-34 compact. One ride I do a couple times a week involves a long straight downhill that I usually bomb down in 52-12. Thought was that the 50-11 would keep me pretty much the same.
I assume the only difference between the PG 1070 and the PG 1050 is weight? If so I will play around and see which works best.
Generally on long flat stretch I do around 22-23mph @ 85 rpm. I will check a gear calculator to see what makes the most sense and if I can live without the 14.
