I have used Neos and Stealth with TTech.No real difference to the Hawk/Spirit.The Hawk is very light of course, so weight/balance issues are more of a factor.I prefer using the heavy ttech grips with red rat covers as it puts a nice weight right in your hand and against the skin.I find the hawk too light.As Limey says, you need to add a volt or two to compensate for the extra resistance of the ttech cartridges.The ttech imho is best with Direct Drives or hard hitters with no give (or very little).Given the Bishop is similar to the Neos, i would bet that it would be a great combo.
