I am using an older set of REI twist lock poles with the shock absorbers and they work great. Never have any issues. I am A big clumsy guy too... in other words I get my money's worth out of them LOL.
black diamond flip locks. Can find on amazon for around $80 a pair.http://www.amazon.com/Black-Diamond-Trail-Compact-Trekking/dp/B001UJENCQ
I use Leki Super Makalu's with anti-shock and cork grips. I like them a lot and wouldn't consider any poles that didn't have the anti shock. I also like 3 piece so that they can get pretty small. I have not had any issues with the twist lock on mine and have owned them for ~6 years. The 2 poles really help going downhill when heavily loaded. I also recommend getting the rubber tips for being quieter.
