DonDoritoHonestly as someone who has played thousands of hours of bhop on cs:s what real reason is there to bhop/surf on tf2. It just feels so much better on cs:s
there are certain tricks you can do on tf2 that you can do on css, its the reason you will see top 10 runs utilizing crouch boosting
theres a skip on badges that you can hit on tf2 than you cant even dream of hitting on css
+ the reason i spent so much time on rehopped, getting prs and wrs is because i preferred the community there, plus its a lot more relaxing imo; though css has low grav bhopping adn that is just so wholesome and relaxing to goof around on
