Tama TTL10 Tension Lock 10pcs

Bought first set of them few years for studio work (not all drums' tuning keep very stable when you hit hard), they do their job around 95% of the time, tuning is keeping solid for much longer and seems like tuning is loosing more because of wear of drumheads not tension rods spinning.
However they do have few cons:
1. they get lost quite easily, especially if you bring your drums to gigs(both because of vibration and the fact that they are not holding too tight on tension rods)
2. they have angles where they are working and angles where they are slipping, so at sometimes they won't do their job at all, and i found that pretty frustrating with some more "harder to tune" drums because few degrees on tension rods really make huge difference.
Anyway, bought another set because they still do the job.
