Rollback activity in workflow

[G Balaji]

Hi,

I have a workflow running on a custom table extended from task. There is an approval activity and when approver rejects the requests he adds notes/comments to requestor. Requestor could edit his request based on the comments/notes and request back again. In this use-case, which would be the best practice ?

1. Rollback to activity

2. I have implemented(pls refer to the attachement)

Thanks.
