Proline question

[detroitchild]

Coaches,

Do any of you use Proline's TTC bases? I find that the Proline TTC's are very unstable and I've not had any success in tweaking them for anything. Most (All?) coaches I know just use the dials in the Miggle shells. I do this and this leaves me with a bunch of useless Proline shells.

Are any of you using them successfully? Have you had any success tweaking them?
