I am currently in the process of having the Warrior "upgraded" to the Bold Warrior/180hp conversion. I have been offered the option of nickel vs steel cylinders and just wanted a few opinions of the good and the bad of either. I can get the steel sooner but am not necessarily in a hurry as we still have about 150 hours to TBO. My sons are flying it about 30-50 hours a month right now (which may slow down due to winter wx), so it won't take long to burn the remaining hours. Is nickel worth the wait?
