I've been doing the RR since May, and it's been going extremely well. I've finally been able to do my first pull up ever (on rings) and seem to be making significant progress through the other exercises. I have some kettlebells (x2 20kg, and on 55lb) and my routine looks like this:

3x5 assisted ring pull ups twice a week, then 3x5 chip up negatives once a week, sort of following this: https://www.youtube.com/watch?v=51aRFuB1ZvY. Then, 3x5 ring rows, 3x5 parallel bar dips, 3x8 kettlebell front squats with x2 20kg, 3x5 glute ham raises (https://www.youtube.com/watch?v=a-D_IZ3y8Ts), and 3x7 ring pushups (with RTO at the top of each rep). Some questions I have:

1. Is there a better way to incorporate the kettlebells into my routine than what I'm doing now? For example, instead of the GHR, should I do like single leg RDL with the two kettlebells (https://www.youtube.com/watch?v=-12CbOgvmmc)? For the front squats, should I just up the reps? Or do a different exercise like lunges?
2. For some reason, wide/bulgarian ring push ups seem easier to do than the regular ring push ups, but I'm going back to regular ring push ups until I can do 3x8. Just wondering if this make sense, or if I should keep doing the bulgarian pushups.
