Automatic Primary Chain Tensioner - yes or no

[fxst-rider]

If you have one of the three available automatic primary chain tensioner devices, which one do you have and why.

If you do not have one of these tensioners, any particular reason.

my 07 has the stock auto tensioner and I bought one for my wifes deluxe, it's going on shortly.

The HD seems like a better thought out unit and I'll never have trouble getting spare shoes for it if ever needed.
