What is the best grappling dummy available for submission and bjj training? I know there is no substitute for a live coaching partner, however for those times i do not have a partner and wish to train submission technique and ground work how helpful would a grappling dummy be? And which bjj dummy would be the closest to a live person? I have read this forum thread and few websites: this grappling dummy buying guide, submission master review and this website, but still can't decide which one to buy. UPDATE: After a lot of reading - Submission Master looks most promising - check out their website.
