A Cautionary Tale
Be careful with tele bindings with 4 drill holes - I ripped these bindings off one of my skis (K2 sidestashes) skiing steep, firm snow last season. I proceeded to slide on my head and back through rocks, fortunately walking away with a only a bruised ego and a long hike out on one ski. After 15 years of tele-ing and multiple binding pull-outs with targa and bd's that was the last straw. I locked the heel down since then and am loving it. In my opinion, tele bindings are a dangerous liability and have not evolved enough to accommodate big boots, fat skis and fast turns. That said, think carefully about you and your touring partner's safety, rescue issues/challenges before you head out touring with teles.
