I find those two to have a little more friction than wood shafts when not using a glove. I use a Cynergy and have only shot around with a revo a few times. I would say they are pretty similar in friction, but can't fully comment on that. I will say I never used a glove until 2020, thought I would never be able to get used to one but the pandemic allowed me time to practice and adjust without losing real time matches. After I adjusted some bridge hand positions on certain shots, it was way better using a glove. It allows for a consistent feel no matter the conditions. There is a reason that more than 90 percent of the pros use a glove. It's one of the reason my game jumped up pretty considerably the past couple of years.
