"I have BD Trail poles. They are heavy by BPL standards, at 17 oz/pr. Their good points, for me, are: robustness, flicklock ease and reliability, adjustability, and comfort. Although I wish they were lighter, I don't baby my poles, and I can't afford to replace carbon poles like GG LT4s on the regular."
All of that. I use Black Diamond's Trail model, also, and like them very much. Need the durability as I'm constantly going off-trail to ramble up and down gorges and follow waterways, and the adjustability for setting my TT Notch at different heights to cope with weather. Love the grip extension for steep climbs, too.
Never noticed the weight. They've been like an extension of my arm for years.
Just ordered a replacement set(best review you can give something), since I lost one last week into a place it couldn't be retrieved from while being a little blasé about life and limb.
Recently bought my girlfriend the Trail Compacts, which are the same thing, just shorter overall and with a smaller grip and shorter extension.
Planning to use my loaners all through next week, since my new Trails probably won't get here in time.
BD Trail Backs that were <$40 from Sierra Trading Post. Not a bad budget pole, I suppose, but they lack the grip extension, have a less comfortable grip, and less padding on the straps, so the Trail is well worth the extra cost.
