The newest style cranks only has room for one slug, after I got my new one slugged, I compared it vs the double slugged crank from Bouchie, the Bouchie crank still weighed a bit more but they are very close. In my 40 hydro I am currently running the new crank with it slugged from Kent Ballard and I have had zero failures, he does great work.
 
Curious, how does the CMB .45 V-5 compare to the current .45 RS EVO, and .45 M-Line engines? No comparison? Close in performance?

The V5 supposedly has more torque, due to the under square bore/stroke ratio. However, theory can be somewhat deceiving.
I have run all 3 of the combinations mentioned in the same D Hydro.
What we found is the RS EVO platform can swing more prop.
Could this be due to the higher rotating mass, hence greater inertia, with the RS EVO platform?... that's what we tend to think.
We did add 2 looper window ports to the V5 (stock timing) in an effort to get more fuel per cycle into the chamber, and it seems to have increased torque significantly.
But, we need to test more with the bigger 2200 and 2300 series ABC's to comment further. Strut depth also plays a significant role, too
 
I have run the v5, evo , and 45 blue head cmbs also in the same d hydro. The v5 and the blue head have very similar results- same props, sane speed, But the EVo is faster, throws the same props with no sag and launchs better. I think it is superior. Same results in my sport40
