I stopped brvr and strava subs to save a bit of money just cos they all start adding up , brvr didnt do anything more than rouvy , strava I do miss cos the free version doesnt give as much information ( nor should it I guess ) it is good how the different platforms solve their problems . Zwift let people gather momentum to breakneck speeds just free wheeling , rouvy has a max speed (44.7) you can reach but you can reach it quicker if you put more effort in , rgt had you breaking if a corner came up so on hairpins you had to pedal out of them to get speed back up before it stopped you again and bkool has me ( dont know about others ) pedalling as hard downhill as I do uphill with not much reward ( certainly a workout but it does grate a bit in a race situation ) I know there is an advantage being heavier going downhill in real life but I have never been dropped irl because of difference in weight when drafting someone else - I have been dropped like a stone once it becomes technical due to lack of skill and kahonies. please dont think this is a dig at bkool , its not , I know the difference in the platforms and thats the way it is - they are all 'quirky'- at the minute I have been doing challenges on rouvy that has been more what I am aiming for at the moment , once I have got back to the fitness I want then I will shake it up a bit and see if you will find a space for me - as bkool is a sub I haven't dropped
